CSS Snapshot 2026
ReferenceThe list of specs that together make up CSS as it stands in 2026.
The CSS Snapshot 2026 is a W3C Group Note, published 18 September 2026, that lists which CSS specifications made up CSS as of that year. It sorts modules by stability: stable, reliable Candidate Recommendations, fairly stable with limited testing, and roughly interoperable.
It also lists features cleared for release before their spec reached Candidate Recommendation, such as aspect-ratio, :is(), :where(), :has() and color-mix().
