== [css-2025][css-cascade-5] Add CSS Cascade 5 to Reliable CRs ==
Splitting the discussion from #9770 for adding [CSS Cascade 5](https://www.w3.org/TR/css-cascade-5/) to the Reliable Candidate Recommendations section of the CSS Snapshot 2025.

Data to consider:

Current status: WD (last published: 13 January 2022), ED from  28 August 2023
[WPT](https://wpt.fyi/results/css/css-cascade?label=master&label=experimental&aligned&q=label%3Ainterop-2022-cascade): passing tests (experimental): Chrome: 606, Edge: 606, Firefox: 626, Safari: 625; [interop](https://wpt.fyi/results/css/css-cascade?label=master&label=experimental&aligned&q=label%3Ainterop-2022-cascade%20and%20all(status%3Apass)): 573 / 625 (91.7%)
Current Snapshot section: -
Open issues: [on GitHub](https://github.com/w3c/csswg-drafts/issues?q=is%3Aopen+is%3Aissue+label%3Acss-cascade-5): 22 (~5 substantial for that spec. level), [in spec.](https://drafts.csswg.org/css-cascade-5/#issues-index): 2

Summary: Very high interoperability, many open issues but only few substantial to spec. level, though spec. only in WD.

Notes: Needs to move to CR first. Level 4 in Official Definition.
