Minutes CSS Values Breakout 2025-09-24
- Resolved: Make type(`url`) invalid in the attr() function (for now) (Issue #5079: attr()’s url type seems wrong)
- Resolved: Simplify as much as possible (combining items when it can) for computed value (Issue #12290: Computed (vs used) value of mix() functions)
- Resolved: Work on this in the next level (in consideration of all the complications outlined above) (Issue #11941: Allow `if()` in descriptors)
- Resolved: type() values are parsed just as in custom properties. Other attr() type values (units % etc) are literals. Add a ‘number’ keyword for literal numbers (Issue #12479: Clarify how `attr-unit` should be parsed)
- Resolved: Add color-scheme() test to both @container queries and if(). Open issue on what color-scheme() returns when used in color-scheme property (Issue #10577: Using `if()` to do dark/light switching of image urls)
- Resolved: Explore options for making a syntactic distinction between input and interpolation options (Issue #12348: *-interpolate() grammar can lead to confusing values)
