The Cascading Style Sheets (CSS) Working Group has published a Candidate Recommendation of CSS Counter Styles Level 3. It adds new built-in counter styles to those defined in CSS 2.1, but, more importantly, it also allows authors to define custom styles for list markers, numbered headings and other types of generated content.
At the same time, the Internationalization Working Group has updated their Working Draft of Predefined Counter Styles, which provides custom rules for over a hundred counter styles in use around the world. It serves both as a ready-to-use set of styles to copy into your own style sheets, and also as a set of worked examples.
The W3C i18n Working Group has published a new Working Draft of Predefined Counter Styles. This document describes numbering systems used by various cultures around the world and can be used as a reference for those wishing to create user-defined counter styles for CSS. The latest draft synchronizes the document with changes to the related document CSS Counter Styles Level 3, for which a second Last Call is about to be announced. If you have comments on the draft, please send to firstname.lastname@example.org.
