This is a page from the Cascading Style Sheets Working Group Blog. Some other places to find information are the “current work” page, the www-style mailing list, the Future of CSS syndicator, and the issue list on Github.
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 has published a Candidate Recommendation and invites implementations of CSS Cascading and Inheritance Level 4. This CSS module describes how to collate style rules and assign values to all properties on all elements by way of cascading (choosing a winning declaration among many) and inheritance (propagating values from parent to child).
Additions to Level 4 include:
revert keyword, which rolls back the cascade to the previous origin. E.g.
* { all: revert; } /* wipe out the entire set of author-level styles */
supports() syntax for conditional @import rules. E.g.
@import "fallback.css" supports(not (display: flex));
There have been no changes since the September LCWD.
As always, please send any feedback to the (archived) public mailing list www-style@w3.org with the spec code ([css-cascade]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
