[CSSWG][css-contain-1] REC of CSS Containment Module Level 1

The CSS WG has published the CSS Containment Module Level 1 as a W3C Recommendation

    https://www.w3.org/TR/css-contain-1/

This CSS module describes the contain property, which indicates that the element’s subtree is independent of the rest of the page. This enables heavy optimizations by user agents when used well.

This document is now a W3C Recommendation. As such, it has received the endorsement of W3C Members and the Director. W3C recommends the wide deployment of its Recommendations as standards for the Web. The W3C Royalty-Free IPR licenses granted under the W3C Patent Policy apply to W3C Recommendations.

Significant changes from earlier drafts are listed at:

Further development will happen in the next level of this specification,
