Separator Block: Add support for wide/full-width versions

[kjellr]

It would be interesting to add support for wide/full alignments to the separator block. This could allow folks to better align it to nearby content.

Current:

Example of a wide-width separator block:

Or even something like this:

Hi @kjellr @beafialho, do you mind if I ask which theme you are using. Full or wide width support might be at the theme level. Whatever it is, I might send PR. Thank you.

I've been playing around with this and have a PR - but the one thing I've run into that I'm not sure about.

Using the 'wide' style for HR is an option themes can use to make the separator full/wide width but is left up to the distinction of how the theme styles the is-style-wide class.

Adding the option to set an alignment potentially conflicts with this. Do we think that is a problem? Or is it up to the theme's discretion how to handle this?

Functional Example using TwentyTwenty:

• Using align options - it renders them at the widths expected.

• Switching all 3 Separator blocks to use the 'Wide' style overides the align value:

I took the screenshots with the Gutenberg Starter Theme. No theme currently implements full/wide control for the Separator block at the moment since it's not an option in Gutenberg.

I think in the context of a change like this, the "wide" label for that block style is a little confusing. 😕

In general though, if a feature like this is added, it will ultimately be left up to themes to correctly implement in the front end. I did some light testing against your PR, and both Twenty Twenty and Twenty Nineteen will need some fixes to get it working right. This change would likely require a (brief) dev note to give folks a heads up.

This makes sense. What would the process normally be for this?

Agreed - does that make this a bigger change in regard to thinking about the Style options as well?

There's a Needs Dev Note tag that we can add to the PR if/when it's merged, and then one of us would probably write up a short description of the change when it gets released.

Let's get some feedback from the rest of the design team about this part.

I do think that most blocks should have alignment options that might be work a little different depending on which block it is used in. Using alignment for the separator block seems like a nice creative way of changing the size of the line. I have also added the issue to the Slack design channel to get additional feedback from other designers.

Of course another way would be to use a kind of slider with percentage/pixels/etc. Where the user can define the width (should also be height) of the line.
