GOV.UK Frontend v4.4.0
New features
Change the Button component's background and text colour
For non-GOV.UK branded websites, you can now change the Button component background and text colour.
To change the Button component background colour, set the $govuk-button-background-colour
Sass variable.
To change the Button component text colour, set the $govuk-button-text-colour
Sass variable.
@import "node_modules/govuk-frontend/govuk/base";
$govuk-button-background-colour: govuk-colour("yellow");
$govuk-button-text-colour: govuk-colour("black");
@import "node_modules/govuk-frontend/govuk/components/button/index";
This was added in pull request #2752: Change the Button component background and text colour. Thanks to @NickColley for this contribution.
Localise the navigation menu toggle button
When using the header Nunjucks macro, you can now translate the text of the mobile navigation menu toggle button by using the menuButtonText
parameter.
You should avoid lengthy values for the menuButtonText
parameter. If the text is too long it can overflow and cause visual issues.
This was added in pull request #2720: Add parameter to localise mobile menu toggle button.
Localise the character count's textarea description/fallback text
When using the character count Nunjucks macro, you can now translate the description of textarea by using the textareaDescriptionText
option.
This text is announced by screen readers when the character count input is focused. It's also displayed visually as a fallback if JavaScript is not available.
This was added in pull request #2742: Add ability to customise character count fallback text, and the option renamed to textareaDescriptionText
in pull request #2915.
Localise the character count's counter message
You can now translate the text shown by the character count component to inform users of:
- when they have reached the maximum number of characters or words
- the number of characters or words over or under the allowed maximum
The Nunjucks macro accepts new options so you can customise each message. You can:
- Use
charactersAtLimitText
orwordsAtLimitText
to provide the text that shows when users have reached the limit. - Use
charactersUnderLimitText
orwordsUnderLimitText
to provide the text that shows when users are under the limit. The component will pluralise the message according to the configured locale and the number of characters or words remaining. - Use
charactersOverLimitText
orwordsOverLimitText
to provide the text that shows when users are over the limit. The component will pluralise the message according to the configured locale and the number of characters or words remaining.
You'll find guidance about the plural forms in our documentation about localising GOV.UK Frontend. The component will replace %{count}
with the number of characters over or under the limit.
If you're not using Nunjucks macros, you can use data-* attributes to provide these translations. Within the attribute value, any quotation marks or other characters reserved by HTML needs to be converted into their HTML entity equivalents.
You can:
- use
data-i18n.characters-at-limit
ordata-i18n.words-at-limit
for when users are at the limit - configure the text that informs the end user they are under the character or word limit, by using
data-i18n.characters-under-limit.{other,many,few,two,one,zero}
ordata-i18n.words-under-limit.{other,many,few,two,one,zero}
, with one suffix for each plural form required by your locale - configure the text that informs the end user they are over the character or word limit, by using
data-i18n.characters-over-limit.{other,many,few,two,one,zero}
ordata-i18n.words-over-limit.{other,many,few,two,one,zero}
, with one suffix for each plural form required by your locale
You can also provide these messages using a JavaScript configuration object when creating an instance of the component or initialising all components. See our guidance on localising GOV.UK Frontend for how to do this.
This was added in the following pull requests:
- #2895 Add macro options to configure CharacterCount translations
- #2887 Allow CharacterCount component to receive i18n config via JS
Localise the character count's input description for assistive technologies
When configuring the character count's limit in JavaScript, you can customise the description provided to assistive technologies when users focus the input (so it indicates the overall limit of characters or words).
Depending on the plural form required by your locale, you can pass the description in the HTML using the data-i18n.textarea-description.{other,many,few,two,one,zero}
attribute on the element to provide the text to set as the description.
You can also provide these messages using a JavaScript configuration object when creating an instance of the component or initialising all components. See our guidance on localising GOV.UK Frontend for how to do this.
This was added in pull request #2915.
Localise the accordion's toggle buttons
You can now translate the text of the accordion component's show and hide toggle buttons.
When using the Nunjucks macro, you can use the new showSectionText
and hideSectionText
parameters to customise the text of the 'show' and 'hide' toggles in each section.
You can also use showAllSectionsText
and hideAllSectionsText
parameters to customise the text of the toggle at the top of the accordion.
If you're not using the Nunjucks macro, you can customise these using data-* attributes. Within the attribute value, any quotation marks or other characters reserved by HTML needs to be converted into their HTML entity equivalents.
data-i18n.show-section
data-i18n.show-section-aria-label
data-i18n.hide-section
data-i18n.hide-section-aria-label
data-i18n.show-all-sections
data-i18n.hide-all-sections
You can also change this text for all instances of the Accordion using a JavaScript configuration object. See our guidance on localising GOV.UK Frontend for how to do this.
This was added in pull requests:
- #2818: Add support for localisation via data-* attributes to Accordion component
- #2826: Add support for localisation via JavaScript configuration to Accordion component
Suppress deprecation warnings
You can now suppress warnings from deprecations within GOV.UK Frontend by updating the $govuk-suppressed-warnings
map in Sass. Every deprecation warning will now include a warning "key" which you can use in the following code, placed at the root of your sass project:
$govuk-suppressed-warnings: (
deprecated-feature
);
This was added in #2911 Add warning suppression functionality
Configure components in JavaScript
JavaScript components can get the same configuration options in 2 ways - through data attributes, as before, and now when creating an instance. These components are:
- the
Button
component, for itspreventDoubleClick
option (matchingdata-prevent-double-click
) - the
CharacterCount
component, for itsmaxlength
,maxwords
andthreshold
options (matchingdata-maxlength
,data-maxwords
anddata-threshold
, respectively) - the
ErrorSummary
component, for itsdisableAutoFocus
option (matchingdata-disable-auto-focus
) - the
NotificationBanner
component, for itsdisableAutoFocus
option (matchingdata-disable-auto-focus
)
You can leave out these configuration options when using the Nunjucks macro and provide configuration when:
- creating a component, in a configuration object as second argument
- initialising components in bulk using
initAll
For example:
// Creating a single instance
var button = document.querySelector('[data-module="button"]')
new GOVUKFrontend.Button(button, {preventDoubleClick: true})
// Or initialising components in bulk
GOVUKFrontend.initAll({
button: {
preventDoubleClick: true
}
// Or, for the other components,
// characterCount: {/* options */},
// errorSummary: {/* options */},
// notificationBanner: {/* options */}
})
You can find more information about component configuration in GOV.UK Frontend documentation.

Recommended changes
Update the HTML for the error summary
If you're not using the Nunjucks macros, you can improve the experience for screen reader users by making these changes to the error summary markup:
- Remove
aria-labelledby="error-summary-title"
androle="alert"
from the parent element (govuk-error-summary
) - Add a
div
wrapper around the contents ofgovuk-error-summary
with the attributerole="alert"
- Remove
id="error-summary-title"
from the error summaryh2
(govuk-error-summary__title
)
This will enable screen reader users to have a better, more coherent experience with the error summary. It will make sure users of JAWS 2022 or later will hear the entire contents of the error summary on page load and therefore have further context on why there is an error on the page they're on.
This was added in pull request #2677: Amend error summary markup to fix page load focus bug in JAWS 2022.
