CSS Positioning Level 3 Rewritten

The CSS Working Group has published an updated Working Draft of CSS Positioning Level 3. This module contains defines coordinate-based positioning and offsetting schemes of CSS: relative positioning, sticky positioning, absolute positioning, and fixed positioning.

This update completely rewrites the entire spec for editorial clarity, technical precision, and compatibility with CSS Box Alignment, CSS Writing Modes, and CSS Display. There should be no differences in behavior from CSS2.1, so please report any inconsistencies as errors. (We’ve temporarily preserved some of the old absolute-positioning text for comparison.)

We’ve also posted a minor update of CSS Display Level 3 to better integrate the cross-references across the two specs and ensure that all of the relevant CSS2.1 prose (particularly around the definition of containing block) as been uplifted to Level 3.

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-position-3]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
