The CSS Working Group has published an updated Working Draft of the CSS Overflow Module Level 3. This module contains the features of CSS relating to scrollable overflow handling in visual media, including the overflow property and its longhands; line-clamp, its longhands, and its legacy pre-standard syntax; and the text-overflow property. A few additional features introduced in support of the CSS Containment Module are also defined: overflow: clip and the overflow-clip-margin property.
Major changes since the previous Working Draft include:
scroll-behavior and scrollbar-gutter properties from CSSOM View and CSS Overflow Level 4, respectively.overflow-clip-margin.See the Changes section for further details.
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-overflow-3]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
