Interop 2022
summary
Major browser vendors coordinate to fix 15 key areas of CSS interoperability, using the web-platform-tests suite and a public dashboard that turns passing tests into browser scores. Concrete wins include cascade layers landing across engines, aspect-ratio and flex gap implemented, and subgrid in Firefox and Safari Technology Preview with Chrome work underway; some areas reach >95% on experimental builds while others remain under investigation. The project tracks failing tests, implements fixes, and reports measurable cross‑browser progress.
