The CSS WG has published an updated Working Draft of the CSS Containment Module Level 2:

    https://www.w3.org/TR/css-contain-2/

This CSS module describes the contain property, which indicates that the element’s subtree is independent of the rest of the page, as well as content-visibility property, which controls whether or not an element renders its contents at all. This enables heavy optimizations by user agents when used well.

This update publishes about two years worth or refinements, bug fixes, and clarifications, getting closer to stability. A number of open issues remain to be addressed, but the fundamentals are in place.

Significant changes are listed at:

  https://www.w3.org/TR/2022/WD-css-contain-2-20220917/#changes

Please review the draft, and send any comments to this mailing list,
<www-style@w3.org>, prefixed with [css-contain-2] (as I did on this
message) or (preferably) file them in the GitHub repository at
  https://github.com/w3c/csswg-drafts/issues

For the CSS WG,
—Florian Rivoal
