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 First Public Working Draft of CSS Will-Change. This module defines a single property, “will-change”, which allows the author to provide hints to the browser about what aspects of an element will change in the near future, allowing browsers to set up appropriate optimizations ahead of time, before the change occurs.
Implementation is already proceeding in Firefox and Blink-based browsers (Chrome, Opera), and this specification is expected to advanced to Candidate Recommendation quickly. Any nitpicks on the precise semantics of the property are welcome.
As always, please send feedback to the (archived) public mailing list firstname.lastname@example.org with the spec code (
[css-will-change]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
