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 an updated Candidate Recommendation of CSS Values and Units Level 3. This CSS module describes the common values and units that CSS properties accept and the syntax used for describing them in CSS property definitions.
Changes since the 2016 Candidate Recommendation include
ur()s as representing an invalid URL
url()s because apparently browser engines can’t properly handle updating the computed values of relative url()s when the page’s URL is changed.
A Disposition of Comments is also available. Please send feedback by either filing an issue in GitHub (preferable) or sending mail to the (archived) public mailing list www-style@w3.org with the spec code ([css-values-3]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
