Description Sebastian Zartner 2023-05-01 14:51:58 PDT

CSS Cascading 4 defines a supports() syntax for @import rules allowing support-dependent importing of other style sheets. See https://drafts.csswg.org/css-cascade-4/#typedef-import-conditions.

This feature is important for different features, especially for those introducing new syntax like CSS Nesting.

Sebastian
