Last Call for Review of Proposed Corrections: CSS Containment Module Level 1

Author(s) and publish date


The CSS Working Group has proposed corrections to the W3C Recommendation of CSS Containment Module Level 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.

Proposed corrections are marked in the document. Comments, including implementation experience, are welcome via GitHub through 10 January 2023.
