What?

Exploration start for #38277

Why?

We should have a way to define via theme.json state based styles for elements (and blocks?).

How?

Just adding a state as a selector mapping to WP_Theme_JSON::ELEMENTS

Testing Instructions

  1. Check out this PR
  2. Set TwentyTwentyTwo as the theme
  3. Edit the theme.json in TwentyTwentyTwo by adding the code below under styles > elements:
"link:hover": {
	"color": {
		"text": "red"
	}
}
  1. Make a link in a post and confirm it is red on hover.

Does this also work in the Site Editor? You might need to update the array here too

Hello!

Just cross-linking to an open style engine PR that generates styles for the existing style.elements.link.color properties.

It currently outputs the link colors as before.

I don't see any conflicts here, and am happy to test things further. Cheers!

This looks like a good start.

I tried this on the Nav block to try and style the :hover effect on all a elements. I thought it wasn't working but then when I forced the :hover state via devtools it worked. Is there a pointer-events stopping this :hover applying via normal mouseover?

const ELEMENTS = array(
'link' => 'a',
'link:hover' => 'a:hover',

I have to confess I was expecting:

"link" {
    "color": {
        "text": "red"
    },
    ":hover": {
        "color": {
            "text": "hotpink"
        }
    }
}

But now I'm thinking what you have looks more like CSS whereas my expectations is more like SASS.

We could also look to auto map the :hover. So from link mapping to a we can automatically create the mapping for link:hover => a:hover. This would also allow us to map for various other pseudo classes such as :focusand:active`.
