Closed firefoxic closed 7 months ago

Description

The font-size-adjust property allows you to make different fonts the same visual size. This is useful when replacing a local font with a custom font, or when different fonts are adjacent on the same line.

This would be a great thing to add to Interop 2024. We should be sure to include all three parts:

The tests are not working correctly if Chrome has not yet added support for font-size-adjust, but passes 88.8% of the tests.... so we need to take a look at the tests.

You should see drastically different test results between: https://wpt.fyi/results/css/css-fonts?label=experimental&label=master&q=font-size-adjust (which tests Chrome dev channel, with --enable-experimental-web-platform-features) and https://wpt.fyi/results/css/css-fonts?label=master&label=stable&q=font-size-adjust (which tests Chrome stable channel).

Ah, that makes sense. Great news.

That means the current experiment scores are: Chrome Dev: 88.8% Firefox Nightly: 100% Safari Technology Preview: 98.5%

There's a chance the scores will be too high to make sense to consider for Interop 2024 — that we have interop before the year starts.

I am skeptical about this. After all, Chrome has had this property behind the flag for years. And I have no hope at all that this will change. My only hope is Interop ❤️

This is a recent progress, please see crbug.com/1219875. @shivamidow @drott

I have pushed font-size-adjust to both Blink and WebKit this year. All necessary pieces are in the review pipeline, so Blink and WebKit will hit 100% soon.

Blink:

WebKit:

Is there similarly positive news regarding size-adjust #542 ?

drott commented 10 months ago

In the process, we should try to get a resolution on https://github.com/w3c/csswg-drafts/issues/8967 CC @svgeesus

The proposed test set includes font-size-adjust-metrics-override.html — which requires support for ascent-override / descent-override, a feature WebKit does not yet support. We'd like this test to not be included, since it's an 'off topic dependency'.
