Specification

https://drafts.csswg.org/css-counter-styles/#counter-style-speak-as

Design docs


https://bit.ly/3kEHluz

Summary & Motivation

A custom counter style can be constructed with a meaning that is obvious visually, but impossible to meaningfully represent via a speech synthesizer or other non-visual means, or possible but nonsensical when naively read out loud. The 'speak-as' descriptor describes how to synthesize the spoken form of a counter formatted with the given counter style.



Blink component

Blink>CSS

Initial public proposal

None

TAG review

N/A; Firefox already shipped it years ago.

TAG review status

Not applicable

Risks



Interoperability and Compatibility

Very low, as we are implementing a well-specified feature that Firefox already shipped years ago, and Safari is positive on.



Gecko: Shipped/Shipping (https://bugzilla.mozilla.org/show_bug.cgi?id=966166)

WebKit: Positive (https://lists.webkit.org/pipermail/webkit-dev/2021-February/031719.html) Safari is positive on the @counter-style rule as a whole, including this descriptor.

Web developers: Strongly positive (https://bugs.chromium.org/p/chromium/issues/detail?id=687225) Developers are positive on the @counter-style rule as a whole, including this descriptor.


Debuggability

N/A; it's an extension to an already shipped feature, @counter-style. Note that we don't have DevTools support for @counter-style yet, as the requirement was imposed after @counter-style was shipped.



Is this feature fully tested by web-platform-tests?

No; will add tests.


Requires code in //chrome?

False

LGTM1

Catching up with Firefox and fixing this pressing issue for developers (especially in non-English languages) makes perfect sense. Thanks for working on this! :)

Thanks for reviewing!

Also a question: What does LGTM on an I2P indicate? Does it mean that when I finish implementation, the I2S will automatically be approved?

Oh sorry, I didn't notice it was just I2P. I think we approved for shipping, so yes you can just go ahead and consider this thread a intent to prototype and ship. :)  (Please update the chromestatus.com entry accordingly also.)
