Do you want to know how the CSS WG works? Fantasai has written about:csswg, An Inside View of the CSS Working Group at W3C.
The CSS Working Group and the SVG Working Group have published a First Public Working Draft of Geometry Interfaces. This specification provides basic geometric interfaces such as DOMPoint, DOMRect, DOMQuad or DOMMatrix used by other modules or specifications.
Implementation is already proceeding in Firefox and prefixed implementations are shipping in Safari, Chrome, Opera and Internet Explorer.
Please send feedback to the (archived) public mailing list firstname.lastname@example.org with the spec code (
[geometry]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
