KevinDoughty has just created a new issue for https://github.com/w3c/csswg-drafts: == Clamping values and additive animation == There is no useful form of additive animation that disallows negative Keyframe values. SVG spec defers clamping for opacity: https://www.w3.org/TR/SVG11/implnote.html#RangeClamping CSS does not. This needs to be specified. Firefox and Chromium behavior differ on additive opacity animation. Firefox (only recently) disallows clamping, while Chromium permits useful behavior: https://bugzilla.mozilla.org/show_bug.cgi?id=1984925 This needs to be extended to include all clamped property values, including but not necessarily limited to width, height, and the new size shorthand. https://github.com/w3c/csswg-drafts/issues/12645 Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/12648 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
