1913301 - Support the Additional “Ready-made” Counter Styles mentioned in css-counter-styles-3

Status: NEW

(Core :: CSS Parsing and Computation, enhancement)

Description

[Jonathan Kew [:jfkthame]]

In 8. Additional “Ready-made” Counter Styles, the current spec draft says that:

As with the counter styles defined in § 6 Simple Predefined Counter Styles, UAs must include these in their UA stylesheet (or at least act as if these rules were defined at that level).

so we should add these to the counterstyles.css sheet.

(At one time, these were regarded as a separate resource that authors could copy into documents as required, but the CSS WG resolved last year that they should be directly supported by the UA.)

As they are now required to be supported, I think this should be documented at MDN. They are currently already mentioned at https://developer.mozilla.org/en-US/docs/Web/CSS/@counter-style.

As they are that many, I don't think it's makes sense to add them all to the browser compat data for @counter-style. Instead, there might be just one "Ready-made counter styles" entry added for them to @counter-style. This may only provide a rough overview of support in case of partial support, though, or come with a long list of hints.
Alternatively, a new compat data entry could be added holding the info for each one of them. This would allow to create a separate page for them with additional info but also requires much more work.
