We have implemented everything of https://drafts.csswg.org/css-counter-styles-3, except: - Image symbols, which no browsers supports, and is 'at-risk' per spec. - 'speak-as' descriptor, which is an accessibility feature. We will ship @counter-style first, and then work with the accessibility team to implement 'speak-as'. Note that screen-reading of existing (predefined) counter styles are unaffected. - 'symbols()' function, which is not part of @counter-style
