Improve range slider design

[melchoyce]

Chatted a little bit with @jasmussen earlier today about the range slider currently in the Gallery block. It's currently using browser defaults. We discussed introducing a custom design to help improve the overall clarity of the column feature. Here's a bunch of ideas:

cc @afercia to make sure whatever we design and build is accessible :)

Nice work! Definitely some great improvements here!

Here is my completely scientific feedback on each ;)

Beautiful sliders! Another thought might be to not display the slider until the user focuses into the value field. This could be helpful when the value needs more description text or a unit value displayed beside it.

Thanks @melchoyce !
Keeping it native (with some CSS improvements) would be the best option for a11y. To maximize interoperability it could be interesting to explore making the blocks-range-control__hint a styled input field, so users can also directly type the number there.
Modern screen readers work pretty well with native range inputs, not sure about speech recognition software /cc @grahamarmfield

About styling, please don't forget it needs a focus style 🙂 it could be the platform native one (meaning: don't use outline: 0) or a custom one. Screenshot taken on windows Firefox + NVDA

Really love the work ongoing here. From everyone. Thanks Mel, Joshua, Brent and Andrea. 🌟🌟🌟🌟🌟 work.

Hi there, I'd like to add two points: Firstly, the last time I tried (a few months ago) the native slider control didn't work with mobile screen readers - Voiceover and/or Talkback I can't remember which. The situation may be better now but that needs to be tested - assuming that Gutenberg is intended for use on smartphones and tablets. A project I worked on for a client recently wanted to use a native slider. After our findings, they also provided a text box as an alternative for mobile screen readers. Secondly, Dragon NaturallySpeaking does have support for drag and drop, so in theory it should work. But once again it would need to be tested. I'm a bit maxxed on client work at the moment but I will try to get some time to have a look. In what situations is the slider used? Regards Graham Armfield

Just add an image gallery in the post and the right sidebar will show the range input to set the number of columns:

[jasmussen]

Though Mel's slider looks great, would Brent's suggestion help address things in case the slider itself still isn't accessible? #1523 (comment)

[afercia]

I'd display both at the same time: range and input field: no surprises and maybe also easier?

[melchoyce]

Questions about focus: should there be a focus on the whole element, as well as on the toggle? Or could we just add a focus to the toggle itself, if that's possible?

[afercia]

@melchoyce I think users just need to clearly see that something has focus and so that it's actionable. Whether it's the whole "track" or the "thumb" (or whatever it's called :) ) could work.

Edit Media Modal does not reflect number of columns, It is allways on default 3.

Do we feel okay moving forward with this for now, and enhancing as necessary?

[mtias]

Yes, that sounds good.

Do we feel okay moving forward with this for now, and enhancing as necessary?

That is exactly the one I would have preferred from the various mocks for clarity and ability to type. 👍

Yes! Great choice I feel.
