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 the Last Call Working Draft of CSS Masking Module Level 1. The specification describes how to fully or partially hide an object.
Changes since the last Working Draft are listed in the Changes section.
The deadline for comments is Tuesday 10 December 2013. If you need more time, please request an extension before the deadline so that we know to wait for your comments.
As always, please send feedback to the (archived) public mailing list firstname.lastname@example.org with the spec code (
[css-masking]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
