CSS Snapshot 2026 documents the current state of the CSS specification landscape, identifying which modules have reached a level of maturity appropriate for browser implementation and production use. The snapshot consolidates stable features across layout, color, typography, and other CSS modules, providing implementors and authors a single reference for what constitutes well-specified CSS today. For teams maintaining CSS architecture or coding standards, the snapshot is the canonical source for distinguishing settled specifications from experimental or at-risk features. It is particularly useful when evaluating browser compatibility targets or deciding which CSS features can be adopted without risk of specification churn.
