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. This level is focused on completing a precise specification for the existing overflow features, 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 (see https://www.w3.org/TR/css-contain-2/) are also defined: 'overflow: clip' and the 'overflow-clip-margin' property.

The primary changes since the previous Working Draft are:
    * Moving in the 'scroll-behavior' and 'scrollbar-gutter' properties from CSSOM-VIEW and css-overflow-4, respectively.
    * Adding box-edge keywords to 'overflow-clip-margin'.
    * Tightening up requirements around incorporating margins, padding, and zero-area boxes into the scrollable overflow area.

See the Changes section for further details:


Please send any comments to the mailing list <www-style@w3.org>, prefixed with [css-overflow-3] (as I did on this message) or (preferably) file them in the GitHub repository at https://github.com/w3c/csswg-drafts/issues with the spec code [css-overflow-3] and your comment topic in the subject line.

For the CSS WG,
