Change approach to fallback PNG in the header to fix blank data URI from triggering CSP error #2229

The current fallback uses an <image> element, which is interpreted differently depending on whether it’s parsed in the context of SVG or HTML.

We include an xlink:href attribute on the <image> tag to prevent versions of IE which support SVG from downloading the fallback image when they don't need to.

However, this approach has proved problematic – IE11 still requests the fallback PNG when printing, which can cause issues with sessions (#2045) and an attempted fix for that issue by using a blank data uri has now caused further issues with Content Security Policies (#2203).

Switch to the simpler approach of using conditional comments for the header fallback PNG, targeting Internet Explorer 8 specifically. We can then use a good old-fashioned <img> tag.

This does mean that browsers that do not support SVG other than Internet Explorer 8 will not be able to see the crown emblem.

According to Can I Use, the other main browser that does not support SVG that we may need to consider is Android 2.1 - 2.3.

Between 2020-05-14 and 2021-04-30 analytics for GOV.UK shows 6,792 (0.00041%) sessions from 4,343 (0.00119%) users using Android 2.x, out of 577,929,096 sessions from 77,144,107 users.

By comparison, in the same period we saw 36,075 sessions (0.00217%) from 28,963 users (0.00791%) using IE8.

It appears that Android 2.x browsers just omit the SVG entirely – there’s no ‘broken image’ displayed – these users just see ‘GOV.UK’ without the crown:

Given the very low volume of traffic from these browsers, this seems like an acceptable thing to do.

We could have removed the fallback PNG entirely, however our browser support explicitly states support for Internet Explorer 8 (‘although components may not look perfect’) and we know that some service teams do have a disproprtionate number of IE8 users – which is unlikely to be the case for Android 2.

This approach also mirrors the change that GOV.UK Notify have made for their own SVG fallback images in alphagov/emergency-alerts-govuk#39, where they came to the same conclusions.

This PR also tweaks the alignment of the crown with the text, which works independently of the change to the markup:

Opened as draft for now – hoping we can get some data on requests for the fallback PNG from the GOV.UK CDN logs just to check that there are no other browsers that don't support SVG we need to be considering that are not listed on Can I Use.

The CDN log data only shows requests for the fallback image from IE 10, IE11 and Spartan Edge – all of which support SVG and are making requests for the fallback image when they don't need to.

I checked this with the https://github.com/alphagov/notifications-govuk-alerts pages and Content Security Policy (CSP) and seeing no CSP errors.

Note: we use the excellent https://github.com/LandRegistry/govuk-frontend-jinja instead of this (also excellent) code for templating so I made the same changes listed here to our local copy of that code to test it.

This makes sense to me and it simplifies the header code too 👍

We could wrap this change into #1758 to tell users in 4.0 to make the corresponding change in their markup.

Thanks so much all! Our logs will be so much cleaner.

Also IE 8: truly the gift that keeps on giving, however much you try to make it stop.

* Update Node to Active LTS version v16 (Gallium)

Node.js v14 has been in maintenance mode from 19 October 2021. v16 is the active LTS version.

This in turns updates NPM to v8, meaning our lockfile has change to [`lockfileVersion` 2](https://docs.npmjs.com/cli/v8/configuring-npm/package-lock-json#lockfileversion)

This is an internal change that affects development, testing and deployment.

* Add troubleshooting documentation for Node 16, node-sass and M1 machines

If a user has previously installed locally using Node 14 and lower on their M1 machine, they will encounter `node-sass` errors when running `npm install` after pulling this commit.

This adds documentation to deal with those errors.

This should only affect developers.

* Update metalsmith to latest version (2.4.2)

* Install @metalsmith/sass

* Uninstall metalsmith-sass and node-sass

We've installed @metalsmith/sass which uses sass (Dart Sass)
under the hood instead.

* Set `quietDeps` to true and move config to @metalsmith/sass syntax

Move the existing sass config to @metalsmith/sass syntax (uses loadPaths
instead of includePaths)

Set the `quietDeps` flag to true to suppress sass  deprecation warnings for
division (/) and any future deprecations coming from GOV.UK Frontend.

* Add 'src/stylesheets' to sass loadPaths

Dart Sass wasn't able to resolve the import for 'example-init', which
we use within our component example sass.

Telling it to look in 'src/stylesheets' to resolve imports, so it can find
this file.

* Remove node-sass on node v16 troubleshooting docs

We've updated Metalsmith and moved to Dart Sass, so this issue no longer applies (see alphagov#2150)

* Update link text in examples

This aims to make the difference between the `class` and the link text clearer, particularly for people relatively new to HTML.

* Add new team member

* Make help text advice clearer in fieldset guidance

* Add placeholder text info to text input guidance

* Revert town or city field to use address-level2

* Move #top anchor to before the skip link

The ‘back to top’ link takes users to the #top anchor point, which is currently before the navigation but after the ‘skip to main content’ link.

This means you can no longer skip past the navs etc (as per WCAG 2.1 2.4.1 Bypass Blocks [1]) unless you know to press shift + tab to go backwards in the tab order.

Insetead, we want the 'back to top' link to take the user to the very top of the page, so that the next tab will take them to ‘Skip to main content’ (or the cookie banner, if it’s not been dismissed).

We also considered taking the user to the start of `#main` [2], bypassing all of the navigation, but opted instead to move the `#top` anchor to be the very first thing because:

1. The back to top link was introduced in alphagov#687, when we moved from the side navigation and the main content being fixed, independently scrollable panes. This change meant that the side navigation no longer remained within the viewport.

It seems that the intent at the time was that the back to top link would bring the side navigation back into view, rather than providing a convenient way for the user to get back to the top of the main content.

2. Linking to #main makes it harder for users who have to get back to the navigation:

> If you're using a screen reader you could jump between landmarks using hot keys, but if you're just using a keyboard you're kinda just left with the tab key. Maybe I'm missing something, but the only options I could see to get back to the nav would be:
>
> - use TAB to go all the way through the content and footer content until you eventually get back to the top of the page
> - use back to top to get to the top of the main, and then use SHIFT+TAB to reverse through the nav menu
> - refresh the page and use TAB

3. We think users would expect to see the header when using the ‘Back to top’ link, especially if they were aiming for the navigation.

* Add nodeListForEach helper directly into design system

The GOV.UK Frontend ES modules don't make the common (e.g: `nodeListForEach`)
function available to import. We've made this decision intentionally as we never
really intended for `nodeListForEach` to be something we provided.

This introduces a helper.js file which contains `nodeListForEach`. Switch our
JS files to use that helper, rather than the one from GOV.UK Frontend.

* Replace individual JS imports with ES modules initAll

Update pagination guidance

Updated guidance to:

- cover issues raised by working group
- clarify use case for different types of pagination - and when to use 'continue' button and back link instead

* Update what's new and roadmap for 4.2.0

* Update roadmap

* Fixed typo on pagination documentation

* Add paragraph tag to link example

This link example does not include a wrapping element, meaning that some of the text is appearing as default serif text instead of in Transport. As the text above this example states that it is
regarding links at the end of sentences or paragraphs, the example shouldn't be negatively affected by the inclusion of a paragraph.

* Use the official core metalsmith postcss plugin

Metalsmith is being updated fairly regularly now, and have an [official PostCSS plugin](https://github.com/metalsmith/postcss).

We've been blocked on bumping some dependencies because of this (alphagov#2016).

I've run `npm build` and there is one small prefixing change in the resulting CSS, but otherwise it's exactly the same.

* Only toggle details aria attributes if already set

I believe this dates from when the polyfill for the `<details>` element used to be applied in all browsers, and added extra ARIA attributes which always needed to be kept in sync when this script toggled the open state.

However, since GOV.UK Frontend v3.1.0 the polyfill now does nothing in browsers that natively support the <details> elements [1].

This means that once these attributes are set on page load, unless the polyfill is running there is nothing to keep them in sync if the user toggles the details element:

- `aria-expanded` will always be `true`, potentially causing AT to announce the expanded state incorrectly
- `aria-hidden` will always be `false` – although this is likely not an issue as aria-hidden can't make things hidden using display:none 're-appear' in the accessibility tree

Instead, only toggle `aria-expanded` if it is already set on the element (which should only happen if the polyfill has run, in which case the browser does not natively support the `<details>` element).

We also need to re-introduce the `aria-hidden` attribute removed in 8b53583 as when the polyfill runs it currently adds an `aria-hidden` attribute which means the content inside the `<details>` element will be inaccessible even when opened unless we remove it.

Add a comment to try and explain why this code needs to exist.

Patch bump to update some dependencies.

* Bump @metalsmith/sass from 1.0.0 to 1.0.1

Changes: metalsmith/sass@1.0.0...1.0.1

* Adjust link text to GOV.UK image guidance

* Allow start buttons to be forms

Although unusual, there are a few valid circumstances where you might
want to submit a form when pressing the start button. A situation that
came up recently was we wanted to record analytics on when a user
started a service by recording the time that a user presses the start
button, without client-side JavaScript. The implementation for this
involved using the Rails `button_to` helper which generates a form which
POSTs to a route and includes a single `submit` button.

I think this is a valid use case of the start button, so I suggest
changing the wording on this to be slightly more open to the idea of
the start button not being a link.

* Update link to task list Sass file

This file has changed location in recent changes to the Prototype Kit, this updates the URL to no longer 404.

* Override auto-linking with period character

* Move width override classes from spacing to layout

Overriding the width of an element really has nothing to do with spacing, so this guidance make more sense as part of the layout guidance, alongside the documentation about the grid system which uses the same ‘one third’, ‘one half’ concepts.

* Tweak width override guidance for new context

Remove the link to the grid system which is now on the same page and is introduced before the override classes

Remove a reference to the spacing override classes which doesn’t make sense now that they’re on a separate page and the user might not have read about them already.

* Update links to width override classes

* Remove link to archived ethnic groups pattern

The ethnic groups pattern was archived in alphagov#1582.

* Remove broken link in page template guidance

The ‘variables’ and ‘blocks’ tables were merged in alphagov#1311 but this link was missed.

* Remove redundant classes

As noted in alphagov/govuk-frontend#2733, these classes don’t actually do anything.

* Remove extra closing `</tr>` tag

* Swap small and large screen sizes in spacing table

Putting the smaller sizes on the left-hand size seems more logical and fits better with a mobile-first approach.

* Flip order of spacing scale in table

Going from the smallest size to the largest size just makes more sense.

* Fix mismatched heading tags in navigation

* Document the static spacing scale

Fixes alphagov#1210.

* Improve headings for override classes and helpers

* Move section on overrides last

Try to encourage users who are writing their own CSS to use the helpers that we provide rather than the override classes, by making it more likely they’ll read about them first.

* Update link to my talk for more accessible blog

Allows more options to access it as I've made it into a blog post too.

* Tweaks to guidance on helpers

* Tweaks to guidance on override classes

* Bump autoprefixer to 10.4.7

One major version bump. Version 10:

- Uses PostCSS 8
- Removes support for Node.js 6, 8 and 11
- PostCSS is now a peerDependency

None of which affects our installation.

* Replace sass-lint with stylelint

* Add basic stylelint config

The resulting CSS appears to be the same after running `npm run build`.

* Fix SCSS linting errors

* Update logo in header to match GOV.UK Frontend

Mirror the changes that have been made to the Header component in GOV.UK Frontend [1] including:

- using conditional comments for header fallback PNG rather than an `<image` element [2]
- camel-casing the SVG attributes [3]

Fixes alphagov#2280.

* Change to more up to date link

GSS appear to have moved to a new site - the link was pointing at the old (and out of date) archived standard.

* Remove examples for archived ethnic groups pattern

The ‘Ask users for ethnic groups’ pattern was archived in alphagov#1582 [1] (dd77104) when the guidance was moved into the ‘Ask users for equality information’ pattern.

New examples were created for the equality information pattern, but the existing examples and the SVG included in the guidance were not removed from the repo.

Remove the examples and the SVG previously included in the archived ethnic groups pattern.

* Update Node to Active LTS version v16 (Gallium)

Node.js v14 has been in maintenance mode from 19 October 2021. v16 is the active LTS version.

This in turns updates NPM to v8, meaning our lockfile has change to [`lockfileVersion` 2](https://docs.npmjs.com/cli/v8/configuring-npm/package-lock-json#lockfileversion)

This is an internal change that affects development, testing and deployment.

* Add troubleshooting documentation for Node 16, node-sass and M1 machines

If a user has previously installed locally using Node 14 and lower on their M1 machine, they will encounter `node-sass` errors when running `npm install` after pulling this commit.

This adds documentation to deal with those errors.

This should only affect developers.

* Update metalsmith to latest version (2.4.2)

* Install @metalsmith/sass

* Uninstall metalsmith-sass and node-sass

We've installed @metalsmith/sass which uses sass (Dart Sass)
under the hood instead.

* Set `quietDeps` to true and move config to @metalsmith/sass syntax

Move the existing sass config to @metalsmith/sass syntax (uses loadPaths
instead of includePaths)

Set the `quietDeps` flag to true to suppress sass  deprecation warnings for
division (/) and any future deprecations coming from GOV.UK Frontend.

* Add 'src/stylesheets' to sass loadPaths

Dart Sass wasn't able to resolve the import for 'example-init', which
we use within our component example sass.

Telling it to look in 'src/stylesheets' to resolve imports, so it can find
this file.

* Remove node-sass on node v16 troubleshooting docs

We've updated Metalsmith and moved to Dart Sass, so this issue no longer applies (see alphagov#2150)

* Update link text in examples

This aims to make the difference between the `class` and the link text clearer, particularly for people relatively new to HTML.

* Add new team member

* Make help text advice clearer in fieldset guidance

* Add placeholder text info to text input guidance

* Move #top anchor to before the skip link

The ‘back to top’ link takes users to the #top anchor point, which is currently before the navigation but after the ‘skip to main content’ link.

This means you can no longer skip past the navs etc (as per WCAG 2.1 2.4.1 Bypass Blocks [1]) unless you know to press shift + tab to go backwards in the tab order.

Insetead, we want the 'back to top' link to take the user to the very top of the page, so that the next tab will take them to ‘Skip to main content’ (or the cookie banner, if it’s not been dismissed).

We also considered taking the user to the start of `#main` [2], bypassing all of the navigation, but opted instead to move the `#top` anchor to be the very first thing because:

1. The back to top link was introduced in alphagov#687, when we moved from the side navigation and the main content being fixed, independently scrollable panes. This change meant that the side navigation no longer remained within the viewport.

It seems that the intent at the time was that the back to top link would bring the side navigation back into view, rather than providing a convenient way for the user to get back to the top of the main content.

2. Linking to #main makes it harder for users who have to get back to the navigation:

> If you're using a screen reader you could jump between landmarks using hot keys, but if you're just using a keyboard you're kinda just left with the tab key. Maybe I'm missing something, but the only options I could see to get back to the nav would be:
>
> - use TAB to go all the way through the content and footer content until you eventually get back to the top of the page
> - use back to top to get to the top of the main, and then use SHIFT+TAB to reverse through the nav menu
> - refresh the page and use TAB

3. We think users would expect to see the header when using the ‘Back to top’ link, especially if they were aiming for the navigation.

* Bump govuk-frontend to 4.1.0

* Add nodeListForEach helper directly into design system

The GOV.UK Frontend ES modules don't make the common (e.g: `nodeListForEach`)
function available to import. We've made this decision intentionally as we never
really intended for `nodeListForEach` to be something we provided.

This introduces a helper.js file which contains `nodeListForEach`. Switch our
JS files to use that helper, rather than the one from GOV.UK Frontend.

Update pagination guidance

Updated guidance to:

- cover issues raised by working group
- clarify use case for different types of pagination - and when to use 'continue' button and back link instead

Minor edits for dashes and contractions

Tweaking paragraph breaks

Remove section about saying "page" in labels

By default, "Previous" and "next" do not include "page" so this section is no longer needed

* Remove pagination component from community backlog

* Update what's new and roadmap for 4.2.0

* Update roadmap

Tidying up and reorganising some of our roadmap items in mid-2022.

* Fixed typo on pagination documentation

* Add paragraph tag to link example

This link example does not include a wrapping element, meaning that some of the text is appearing as default serif text instead of in Transport. As the text above this example states that it is
regarding links at the end of sentences or paragraphs, the example shouldn't be negatively affected by the inclusion of a paragraph.

* Indent Nunjucks code

* Use the official core metalsmith postcss plugin

Metalsmith is being updated fairly regularly now, and have an [official PostCSS plugin](https://github.com/metalsmith/postcss).

We've been blocked on bumping some dependencies because of this (alphagov#2016).

I've run `npm build` and there is one small prefixing change in the resulting CSS, but otherwise it's exactly the same.

* Only toggle details aria attributes if already set

I believe this dates from when the polyfill for the `<details>` element used to be applied in all browsers, and added extra ARIA attributes which always needed to be kept in sync when this script toggled the open state.

However, since GOV.UK Frontend v3.1.0 the polyfill now does nothing in browsers that natively support the <details> elements [1].

This means that once these attributes are set on page load, unless the polyfill is running there is nothing to keep them in sync if the user toggles the details element:

- `aria-expanded` will always be `true`, potentially causing AT to announce the expanded state incorrectly
- `aria-hidden` will always be `false` – although this is likely not an issue as aria-hidden can't make things hidden using display:none 're-appear' in the accessibility tree

Instead, only toggle `aria-expanded` if it is already set on the element (which should only happen if the polyfill has run, in which case the browser does not natively support the `<details>` element).

We also need to re-introduce the `aria-hidden` attribute removed in 8b53583 as when the polyfill runs it currently adds an `aria-hidden` attribute which means the content inside the `<details>` element will be inaccessible even when opened unless we remove it.

Add a comment to try and explain why this code needs to exist.

* Bump metalsmith-uglify to v2.4.1

Patch bump to update some dependencies.

* Bump @metalsmith/sass from 1.0.0 to 1.0.1

Changes: metalsmith/sass@1.0.0...1.0.1

* Adjust link text to GOV.UK image guidance

* Allow start buttons to be forms

Although unusual, there are a few valid circumstances where you might
want to submit a form when pressing the start button. A situation that
came up recently was we wanted to record analytics on when a user
started a service by recording the time that a user presses the start
button, without client-side JavaScript. The implementation for this
involved using the Rails `button_to` helper which generates a form which
POSTs to a route and includes a single `submit` button.

I think this is a valid use case of the start button, so I suggest
changing the wording on this to be slightly more open to the idea of
the start button not being a link.

* Update link to task list Sass file

This file has changed location in recent changes to the Prototype Kit, this updates the URL to no longer 404.

* Override auto-linking with period character

* Move width override classes from spacing to layout

Overriding the width of an element really has nothing to do with spacing, so this guidance make more sense as part of the layout guidance, alongside the documentation about the grid system which uses the same ‘one third’, ‘one half’ concepts.

* Tweak width override guidance for new context

Remove the link to the grid system which is now on the same page and is introduced before the override classes

Remove a reference to the spacing override classes which doesn’t make sense now that they’re on a separate page and the user might not have read about them already.

* Update links to width override classes

* Remove link to archived ethnic groups pattern

The ethnic groups pattern was archived in alphagov#1582.

* Remove broken link in page template guidance

The ‘variables’ and ‘blocks’ tables were merged in alphagov#1311 but this link was missed.

* Remove redundant classes

As noted in alphagov/govuk-frontend#2733, these classes don’t actually do anything.

* Remove extra closing `</tr>` tag

* Swap small and large screen sizes in spacing table

Putting the smaller sizes on the left-hand size seems more logical and fits better with a mobile-first approach.

* Flip order of spacing scale in table

Going from the smallest size to the largest size just makes more sense.

* Fix mismatched heading tags in navigation

* Document the static spacing scale

Fixes alphagov#1210.

* Improve headings for override classes and helpers

* Move section on overrides last

Try to encourage users who are writing their own CSS to use the helpers that we provide rather than the override classes, by making it more likely they’ll read about them first.

* Update link to my talk for more accessible blog

Allows more options to access it as I've made it into a blog post too.

* Tweaks to guidance on helpers

* Tweaks to guidance on override classes

* Bump autoprefixer to 10.4.7

One major version bump. Version 10:

- Uses PostCSS 8
- Removes support for Node.js 6, 8 and 11
- PostCSS is now a peerDependency

None of which affects our installation.

* Replace sass-lint with stylelint

* Add basic stylelint config

The resulting CSS appears to be the same after running `npm run build`.

* Fix SCSS linting errors

* Update documentation

* Replace metalsmith-tagcleaner with a custom marked renderer

* Bump marked and  jstransformer packages

Makes sense to bump these as part of this work, since they're being used under the hood to transform our files.

* Document static spacing override classes

Static spacing override classes are being introduced to GOV.UK Frontend (alphagov/govuk-frontend#2672).

Document the new classes so that users know how they work, and how they compare to the existing responsive spacing override classes.

* Change to more up to date link

GSS appear to have moved to a new site - the link was pointing at the old (and out of date) archived standard.

* Remove examples for archived ethnic groups pattern

The ‘Ask users for ethnic groups’ pattern was archived in alphagov#1582 [1] (dd77104) when the guidance was moved into the ‘Ask users for equality information’ pattern.

* Fix matchMedia event listener in IE / Safari < 14

IE 10/11 and Safari >= 5.1 < 14 support `window.matchMedia` but do not support `MediaQueryList.addEventListener`.

Instead we have to use the non-standard (and deprecated) `MediaQueryList.addListener`, which only takes one argument which is the callback function to run when the media query status changes [1].

Test for the presence of the `MediaQueryList.addEventListener` method and then use whichever method is appropriate for the browser.

* Enable aliases for section headings

* Alias section break as hr

* Update What's New for v4.3.0

* Update govuk-frontend to 4.3.0

* Document `opengraphImageUrl` page template option

Document the new `opengraphImageUrl` page template option, added in alphagov/govuk-frontend#2673.

Update the documentation for the `assetUrl` option to make it slightly more generic and remove the recommendation to override by adding another meta tag to the `head` block as users should use the new `opengraphImageUrl` instead.

* Retry failed tests

The "see no evil, hear no evil" approach. This does not address the flaky tests themselves, but sets `jest.retryTimes` to 3, rerunning failed tests and greatly increasing the likelihood of a CI test task passing.

This is speedier (and more automatic) than rerunning a full CI task again, so might be enough if the flakiness isn't easily addressable.

* Fix linting issues

* Update team members list

* Reference cookie banner in updating guidance

We now have a cookie banner component, so we should link to it from this guide.

* Add ‘measuring the value’ talk to community page

* Add in link and download to Mural file

Interaction Designer, Clare Brown ([email protected]) has created an editable Mural template of GOV.UK Design System Flow Diagram for all designers to use.

This will help designers map out their service and/or user journeys at a high-level. The template is based off designs that were created in Miro and hosted on GitHub which can be found here: https://github.com/paulmsmith/govuk-designsystem-flow-diagram-miro.

File needs to be hosted for download, uploaded and have instructions on how people can use the file.

* Remove unused tables option

The `tables` option was removed in Marked v0.7.0 [1] so this doesn’t do anything any more.

[1]: https://github.com/markedjs/marked/releases/tag/v0.7.0

* Remove unused gfm: true from marked config

The documentation for the `pedantic` option [1] says:

> If true, conform to the original markdown.pl as much as possible. Don't fix original markdown bugs or behavior. Turns off and overrides gfm.

Verified that this option is doing nothing by comparing the build output with and without this setting, and there is no difference (other than the obfuscated email address on the community page, which is non-deterministic and so changes with every build):

```
$ diff -r deploy/public-marked-main deploy/public
diff -r deploy/public-marked-main/community/design-system-working-group/index.html deploy/public/community/design-system-working-group/index.html

* Add border to 'preview' / 'archive' banner

We moved the banner when refactoring the nav in 2b6a27b.

Now that the banner is not between the header and the navigation, it makes sense to add the bottom border back to separate the banner from the page content.

Keep the `--no-border` modifier which we use on the homepage when the banner is followed immediately by the masthead.

* Remove redundant app-pane wrapper

When the Design System had an independently scrollable nav and body regions, we used a 'app-pane' flexbox wrapper around the whole site so that the header could be fixed in place above both scrollable regions.

When we simplified the layout and lost the indepedantly scrollable regions we didn't tidy up the wrapper, which isn't really doing anything any more (other than the flex layout causing weird issues like the banner width issue seen in 6c83fde).

Remove the unneccesary wrapper and its classes.

* Remove custom phase banner styles

The `width: 100%` is no longer needed that we're not in a flex context and can be removed.

As it turns out, the margins are being overridden by the `app-width-container` class anyway – and if they weren't being overriden, they'd mean that the phase banner would be flush up against the viewport edges on mobile, which isn't what we want.

* Remove redundant app-pane__content wrappers

The `app-pane__content` class isn't doing anything useful in these layouts and can be removed.

* Split 'category nav' out from app pane CSS

This doesn't really have anything to do with the rest of the 'split pane' CSS, so split it out into its own 'component'.

Whilst we're at it, give it a better name and some context to help explain what it's for and why we need it.

* Rename app-pane classes

* Fix implementation for non-flexbox browsers

* Rename 'pane' to 'split-pane'

* Remove unused CSS

* Stop recommending pattern=[0-9]* on number inputs

We previously recommended using `pattern="[0-9]*"` on number inputs to prompt iOS to display the numeric keypad.

This has been unnecessary since Safari 12.2, when support for the standardised `inputmode` attribute was added to Safari.

We stopped using the `pattern` attribute on the date input component [1] in v4.1.0 (released in May 2022) as the proportion of GOV.UK visitors using versions of iOS 12.x and below had fallen to 0.08% of total traffic.

[1]: alphagov/govuk-frontend#2599

Co-authored-by: Calvin Lau <[email protected]>

* Remove pattern attribute from examples

See previous commit for details.

* Remove use of govuk-exports

We need to use govuk-exports in GOV.UK Frontend as files can be imported multiple files but we only ever want the CSS to be outputted once.

As we're in control of how and where Sass in the Design System is imported, we don't need to worry about this and don't need to use the exports function.

* Remove Sass and class that don't do anything

* Fix more Sass that doesn't do anything

The govuk-visually-hidden has `position: absolute` marked as `!important` and therefore it overrides this, so it can't be doing anything.

* Remove unused app-phase-banner class

* Update package-lock.json

* Remove new GOV.UK pages

* Update Node to Active LTS version v16 (Gallium)

Node.js v14 has been in maintenance mode from 19 October 2021. v16 is the active LTS version.

This in turns updates NPM to v8, meaning our lockfile has change to [`lockfileVersion` 2](https://docs.npmjs.com/cli/v8/configuring-npm/package-lock-json#lockfileversion)

This is an internal change that affects development, testing and deployment.

* Add troubleshooting documentation for Node 16, node-sass and M1 machines

If a user has previously installed locally using Node 14 and lower on their M1 machine, they will encounter `node-sass` errors when running `npm install` after pulling this commit.

This adds documentation to deal with those errors.

This should only affect developers.

* Update metalsmith to latest version (2.4.2)

* Install @metalsmith/sass

* Uninstall metalsmith-sass and node-sass

We've installed @metalsmith/sass which uses sass (Dart Sass)
under the hood instead.

* Set `quietDeps` to true and move config to @metalsmith/sass syntax

Move the existing sass config to @metalsmith/sass syntax (uses loadPaths
instead of includePaths)

Set the `quietDeps` flag to true to suppress sass  deprecation warnings for
division (/) and any future deprecations coming from GOV.UK Frontend.

* Add 'src/stylesheets' to sass loadPaths

Dart Sass wasn't able to resolve the import for 'example-init', which
we use within our component example sass.

Telling it to look in 'src/stylesheets' to resolve imports, so it can find
this file.

* Remove node-sass on node v16 troubleshooting docs

We've updated Metalsmith and moved to Dart Sass, so this issue no longer applies (see https://github.com/alphagov/govuk-design-system/pull/2150)

* Move #top anchor to before the skip link

The ‘back to top’ link takes users to the #top anchor point, which is currently before the navigation but after the ‘skip to main content’ link.

This means you can no longer skip past the navs etc (as per WCAG 2.1 2.4.1 Bypass Blocks [1]) unless you know to press shift + tab to go backwards in the tab order.

Insetead, we want the 'back to top' link to take the user to the very top of the page, so that the next tab will take them to ‘Skip to main content’ (or the cookie banner, if it’s not been dismissed).

We also considered taking the user to the start of `#main` [2], bypassing all of the navigation, but opted instead to move the `#top` anchor to be the very first thing because:

1. The back to top link was introduced in #687, when we moved from the side navigation and the main content being fixed, independently scrollable panes. This change meant that the side navigation no longer remained within the viewport.

It seems that the intent at the time was that the back to top link would bring the side navigation back into view, rather than providing a convenient way for the user to get back to the top of the main content.

2. Linking to #main makes it harder for users who have to get back to the navigation:

> If you're using a screen reader you could jump between landmarks using hot keys, but if you're just using a keyboard you're kinda just left with the tab key. Maybe I'm missing something, but the only options I could see to get back to the nav would be:
>
> - use TAB to go all the way through the content and footer content until you eventually get back to the top of the page
> - use back to top to get to the top of the main, and then use SHIFT+TAB to reverse through the nav menu
> - refresh the page and use TAB

3. We think users would expect to see the header when using the ‘Back to top’ link, especially if they were aiming for the navigation.

Closes #1561

* Make layout name consistent throughout guidance

* Update guidance on footer component

This proposed update:

- adds links to relevant information on privacy notices, cookie pages and accessibility statements
- clarifies copyright and licensing information

Related issues:

https://github.com/alphagov/govuk-design-system/issues/1225
https://github.com/alphagov/govuk-design-system/issues/1306

* Update character count guidance to match new implementation

* Minor edits for consistency

* Clarify and add accessibility information

* Update What's New section for v4.1.0

* Update roadmap

* Add context to JAWS issue

* Bump govuk-frontend to 4.1.0

* Add nodeListForEach helper directly into design system

The GOV.UK Frontend ES modules don't make the common (e.g: `nodeListForEach`)
function available to import. We've made this decision intentionally as we never
really intended for `nodeListForEach` to be something we provided.

This introduces a helper.js file which contains `nodeListForEach`. Switch our
JS files to use that helper, rather than the one from GOV.UK Frontend.

* Replace individual JS imports with ES modules initAll

* Explain that red border depends on exceeding limit

* Add accurate content for email field char limit

* Replace in guidance and examples

-  error message
 - textarea
 - text input
 - character count (including error example)

* Bump actions/setup-node from v2 to v3

* Use node-version-file input to specify node version

actions/setup-node v2.5.0 and above support reading a .nvmrc file itself [[1]].
This lets us simplify our code.

* Make validation guidance language more consistent

* Remove patterns

* Update package-lock.json

* Remove GDS community text

* Update Node to Active LTS version v16 (Gallium)

Node.js v14 has been in maintenance mode from 19 October 2021. v16 is the active LTS version.

This in turns updates NPM to v8, meaning our lockfile has change to [`lockfileVersion` 2](https://docs.npmjs.com/cli/v8/configuring-npm/package-lock-json#lockfileversion)

This is an internal change that affects development, testing and deployment.

* Add troubleshooting documentation for Node 16, node-sass and M1 machines

If a user has previously installed locally using Node 14 and lower on their M1 machine, they will encounter `node-sass` errors when running `npm install` after pulling this commit.

This adds documentation to deal with those errors.

Move the existing sass config to @metalsmith/sass syntax (uses loadPaths
instead of includePaths)

Set the `quietDeps` flag to true to suppress sass  deprecation warnings for
division (/) and any future deprecations coming from GOV.UK Frontend.

* Add 'src/stylesheets' to sass loadPaths

Dart Sass wasn't able to resolve the import for 'example-init', which
we use within our component example sass.

Telling it to look in 'src/stylesheets' to resolve imports, so it can find
this file.

* Move #top anchor to before the skip link

The ‘back to top’ link takes users to the #top anchor point, which is currently before the navigation but after the ‘skip to main content’ link.

This means you can no longer skip past the navs etc (as per WCAG 2.1 2.4.1 Bypass Blocks [1]) unless you know to press shift + tab to go backwards in the tab order.

Insetead, we want the 'back to top' link to take the user to the very top of the page, so that the next tab will take them to ‘Skip to main content’ (or the cookie banner, if it’s not been dismissed).

We also considered taking the user to the start of `#main` [2], bypassing all of the navigation, but opted instead to move the `#top` anchor to be the very first thing because:

1. The back to top link was introduced in #687, when we moved from the side navigation and the main content being fixed, independently scrollable panes. This change meant that the side navigation no longer remained within the viewport.

It seems that the intent at the time was that the back to top link would bring the side navigation back into view, rather than providing a convenient way for the user to get back to the top of the main content.

2. Linking to #main makes it harder for users who have to get back to the navigation:

> If you're using a screen reader you could jump between landmarks using hot keys, but if you're just using a keyboard you're kinda just left with the tab key. Maybe I'm missing something, but the only options I could see to get back to the nav would be:
>
> - use TAB to go all the way through the content and footer content until you eventually get back to the top of the page
> - use back to top to get to the top of the main, and then use SHIFT+TAB to reverse through the nav menu
> - refresh the page and use TAB

3. We think users would expect to see the header when using the ‘Back to top’ link, especially if they were aiming for the navigation.

* Update What's New section for v4.1.0

* Bump govuk-frontend to 4.1.0

* Add nodeListForEach helper directly into design system

The GOV.UK Frontend ES modules don't make the common (e.g: `nodeListForEach`)
function available to import. We've made this decision intentionally as we never
really intended for `nodeListForEach` to be something we provided.

This introduces a helper.js file which contains `nodeListForEach`. Switch our
JS files to use that helper, rather than the one from GOV.UK Frontend.

* Replace individual JS imports with ES modules initAll

Update pagination guidance

Updated guidance to:

- cover issues raised by working group
- clarify use case for different types of pagination - and when to use 'continue' button and back link instead

Minor edits for dashes and contractions

Tweaking paragraph breaks

Remove section about saying "page" in labels

By default, "Previous" and "next" do not include "page" so this section is no longer needed

* Remove pagination component from community backlog

* Update what's new and roadmap for 4.2.0

* Update roadmap

Tidying up and reorganising some of our roadmap items in mid-2022.

* Fixed typo on pagination documentation

* Add paragraph tag to link example

This link example does not include a wrapping element, meaning that some of the text is appearing as default serif text instead of in Transport. As the text above this example states that it is
regarding links at the end of sentences or paragraphs, the example shouldn't be negatively affected by the inclusion of a paragraph.

* Use the official core metalsmith postcss plugin

Metalsmith is being updated fairly regularly now, and have an [official PostCSS plugin](https://github.com/metalsmith/postcss).

We've been blocked on bumping some dependencies because of this (#2016).

I've run `npm build` and there is one small prefixing change in the resulting CSS, but otherwise it's exactly the same.

* Only toggle details aria attributes if already set

I believe this dates from when the polyfill for the `<details>` element used to be applied in all browsers, and added extra ARIA attributes which always needed to be kept in sync when this script toggled the open state.

However, since GOV.UK Frontend v3.1.0 the polyfill now does nothing in browsers that natively support the <details> elements [1].

This means that once these attributes are set on page load, unless the polyfill is running there is nothing to keep them in sync if the user toggles the details element:

- `aria-expanded` will always be `true`, potentially causing AT to announce the expanded state incorrectly
- `aria-hidden` will always be `false` – although this is likely not an issue as aria-hidden can't make things hidden using display:none 're-appear' in the accessibility tree

Instead, only toggle `aria-expanded` if it is already set on the element (which should only happen if the polyfill has run, in which case the browser does not natively support the `<details>` element).

We also need to re-introduce the `aria-hidden` attribute removed in 8b53583 as when the polyfill runs it currently adds an `aria-hidden` attribute which means the content inside the `<details>` element will be inaccessible even when opened unless we remove it.

Add a comment to try and explain why this code needs to exist.

* Bump @metalsmith/sass from 1.0.0 to 1.0.1

Changes: https://github.com/metalsmith/sass/compare/1.0.0...1.0.1

* Adjust link text to GOV.UK image guidance

* Allow start buttons to be forms

Although unusual, there are a few valid circumstances where you might
want to submit a form when pressing the start button. A situation that
came up recently was we wanted to record analytics on when a user
started a service by recording the time that a user presses the start
button, without client-side JavaScript. The implementation for this
involved using the Rails `button_to` helper which generates a form which
POSTs to a route and includes a single `submit` button.

I think this is a valid use case of the start button, so I suggest
changing the wording on this to be slightly more open to the idea of
the start button not being a link.

* Update link to task list Sass file

This file has changed location in recent changes to the Prototype Kit, this updates the URL to no longer 404.

* Override auto-linking with period character

* Move width override classes from spacing to layout

Overriding the width of an element really has nothing to do with spacing, so this guidance make more sense as part of the layout guidance, alongside the documentation about the grid system which uses the same ‘one third’, ‘one half’ concepts.

* Tweak width override guidance for new context

Remove the link to the grid system which is now on the same page and is introduced before the override classes

Remove a reference to the spacing override classes which doesn’t make sense now that they’re on a separate page and the user might not have read about them already.

* Update links to width override classes

* Remove link to archived ethnic groups pattern

The ethnic groups pattern was archived in #1582.

* Remove broken link in page template guidance

The ‘variables’ and ‘blocks’ tables were merged in #1311 but this link was missed.

* Remove redundant classes

As noted in https://github.com/alphagov/govuk-frontend/issues/2733, these classes don’t actually do anything.

* Remove extra closing `</tr>` tag

* Swap small and large screen sizes in spacing table

Putting the smaller sizes on the left-hand size seems more logical and fits better with a mobile-first approach.

* Flip order of spacing scale in table

Going from the smallest size to the largest size just makes more sense.

* Fix mismatched heading tags in navigation

* Document the static spacing scale

Fixes #1210.

* Improve headings for override classes and helpers

* Move section on overrides last

Try to encourage users who are writing their own CSS to use the helpers that we provide rather than the override classes, by making it more likely they’ll read about them first.

* Update link to my talk for more accessible blog

Allows more options to access it as I've made it into a blog post too.

* Tweaks to guidance on helpers

* Tweaks to guidance on override classes

* Bump autoprefixer to 10.4.7

One major version bump. Version 10:

- Uses PostCSS 8
- Removes support for Node.js 6, 8 and 11
- PostCSS is now a peerDependency

None of which affects our installation.

* Replace sass-lint with stylelint

* Add basic stylelint config

The resulting CSS appears to be the same after running `npm run build`.

* Fix SCSS linting errors

* Update documentation

* Replace metalsmith-tagcleaner with a custom marked renderer

* Bump marked and  jstransformer packages

Makes sense to bump these as part of this work, since they're being used under the hood to transform our files.

jstransformer-nunjucks Changelog: https://github.com/jstransformers/jstransformer-nunjucks/blob/master/CHANGELOG.md

* Change to more up to date link

GSS appear to have moved to a new site - the link was pointing at the old (and out of date) archived standard.

* Remove examples for archived ethnic groups pattern

The ‘Ask users for ethnic groups’ pattern was archived in #1582 [1] (dd77104) when the guidance was moved into the ‘Ask users for equality information’ pattern.

New examples were created for the equality information pattern, but the existing examples and the SVG included in the guidance were not removed from the repo.

Remove the examples and the SVG previously included in the archived ethnic groups pattern.

> If you're using a screen reader you could jump between landmarks using hot keys, but if you're just using a keyboard you're kinda just left with the tab key. Maybe I'm missing something, but the only options I could see to get back to the nav would be:
>
> - use TAB to go all the way through the content and footer content until you eventually get back to the top of the page
> - use back to top to get to the top of the main, and then use SHIFT+TAB to reverse through the nav menu
> - refresh the page and use TAB

3. We think users would expect to see the header when using the ‘Back to top’ link, especially if they were aiming for the navigation.

* Minor edits for consistency

* Clarify and add accessibility information

* Update What's New section for v4.1.0

* Update roadmap

* Add context to JAWS issue

* Bump govuk-frontend to 4.1.0

* Add nodeListForEach helper directly into design system

The GOV.UK Frontend ES modules don't make the common (e.g: `nodeListForEach`)
function available to import. We've made this decision intentionally as we never
really intended for `nodeListForEach` to be something we provided.

This introduces a helper.js file which contains `nodeListForEach`. Switch our
JS files to use that helper, rather than the one from GOV.UK Frontend.

* Replace individual JS imports with ES modules initAll

* Explain that red border depends on exceeding limit

* Add accurate content for email field char limit

* Replace in guidance and examples

-  error message
 - textarea
 - text input
 - character count (including error example)

* Bump actions/setup-node from v2 to v3

* Use node-version-file input to specify node version

actions/setup-node v2.5.0 and above support reading a .nvmrc file itself [[1]].
This lets us simplify our code.

Update pagination guidance

Updated guidance to:

- cover issues raised by working group
- clarify use case for different types of pagination - and when to use 'continue' button and back link instead

Minor edits for dashes and contractions

Tweaking paragraph breaks

Remove section about saying "page" in labels

By default, "Previous" and "next" do not include "page" so this section is no longer needed

* Remove pagination component from community backlog

* Update what's new and roadmap for 4.2.0

* Update roadmap

Tidying up and reorganising some of our roadmap items in mid-2022.

* Fixed typo on pagination documentation

* Add paragraph tag to link example

This link example does not include a wrapping element, meaning that some of the text is appearing as default serif text instead of in Transport. As the text above this example states that it is
regarding links at the end of sentences or paragraphs, the example shouldn't be negatively affected by the inclusion of a paragraph.

* Indent Nunjucks code

Attempt to make this file easier to read by indenting Nunjucks code similarly to HTML.

* Use the official core metalsmith postcss plugin

Metalsmith is being updated fairly regularly now, and have an [official PostCSS plugin](https://github.com/metalsmith/postcss).

We've been blocked on bumping some dependencies because of this (#2016).

I've run `npm build` and there is one small prefixing change in the resulting CSS, but otherwise it's exactly the same.

* Only toggle details aria attributes if already set

I believe this dates from when the polyfill for the `<details>` element used to be applied in all browsers, and added extra ARIA attributes which always needed to be kept in sync when this script toggled the open state.

However, since GOV.UK Frontend v3.1.0 the polyfill now does nothing in browsers that natively support the <details> elements [1].

This means that once these attributes are set on page load, unless the polyfill is running there is nothing to keep them in sync if the user toggles the details element:

- `aria-expanded` will always be `true`, potentially causing AT to announce the expanded state incorrectly
- `aria-hidden` will always be `false` – although this is likely not an issue as aria-hidden can't make things hidden using display:none 're-appear' in the accessibility tree

Instead, only toggle `aria-expanded` if it is already set on the element (which should only happen if the polyfill has run, in which case the browser does not natively support the `<details>` element).

We also need to re-introduce the `aria-hidden` attribute removed in 8b53583 as when the polyfill runs it currently adds an `aria-hidden` attribute which means the content inside the `<details>` element will be inaccessible even when opened unless we remove it.

Add a comment to try and explain why this code needs to exist.

Changes: https://github.com/metalsmith/sass/compare/1.0.0...1.0.1

* Adjust link text to GOV.UK image guidance

* Allow start buttons to be forms

Although unusual, there are a few valid circumstances where you might
want to submit a form when pressing the start button. A situation that
came up recently was we wanted to record analytics on when a user
started a service by recording the time that a user presses the start
button, without client-side JavaScript. The implementation for this
involved using the Rails `button_to` helper which generates a form which
POSTs to a route and includes a single `submit` button.

I think this is a valid use case of the start button, so I suggest
changing the wording on this to be slightly more open to the idea of
the start button not being a link.

* Update link to task list Sass file

This file has changed location in recent changes to the Prototype Kit, this updates the URL to no longer 404.

* Override auto-linking with period character

* Move width override classes from spacing to layout

Overriding the width of an element really has nothing to do with spacing, so this guidance make more sense as part of the layout guidance, alongside the documentation about the grid system which uses the same ‘one third’, ‘one half’ concepts.

* Tweak width override guidance for new context

Remove the link to the grid system which is now on the same page and is introduced before the override classes

Remove a reference to the spacing override classes which doesn’t make sense now that they’re on a separate page and the user might not have read about them already.

* Update links to width override classes

* Remove link to archived ethnic groups pattern

The ethnic groups pattern was archived in #1582.

* Remove broken link in page template guidance

The ‘variables’ and ‘blocks’ tables were merged in #1311 but this link was missed.

* Remove redundant classes

As noted in https://github.com/alphagov/govuk-frontend/issues/2733, these classes don’t actually do anything.

* Remove extra closing `</tr>` tag

* Swap small and large screen sizes in spacing table

Putting the smaller sizes on the left-hand size seems more logical and fits better with a mobile-first approach.

* Flip order of spacing scale in table

Going from the smallest size to the largest size just makes more sense.

* Fix mismatched heading tags in navigation

* Document the static spacing scale

Fixes #1210.

* Improve headings for override classes and helpers

* Move section on overrides last

Try to encourage users who are writing their own CSS to use the helpers that we provide rather than the override classes, by making it more likely they’ll read about them first.

* Update link to my talk for more accessible blog

Allows more options to access it as I've made it into a blog post too.

* Tweaks to guidance on helpers

* Tweaks to guidance on override classes

* Bump autoprefixer to 10.4.7

One major version bump. Version 10:

- Uses PostCSS 8
- Removes support for Node.js 6, 8 and 11
