The CSS Snapshot 2026 was officially published as a W3C Group Note on February 26, 2026 , by the Cascading Style Sheets (CSS) Working Group . This milestone provides a consolidated reference point for the current stable state of CSS, serving as an important resource in the ongoing modular evolution of the language. What is the CSS Snapshot? CSS Snapshots are periodic publications from the W3C that collect all the stable CSS specifications and modules into a single, cohesive definition. Rather than a monolithic version like the old CSS2.1 era, modern CSS is built from independent modules (e.g., CSS Color Level 4, CSS Grid Layout, etc.), each advancing at its own pace. The Snapshot defines "the current state of Cascading Style Sheets (CSS) as of 2026" by including modules based on specification stability — meaning how mature and resolved the spec text is — rather than browser implementation or adoption levels. Key purpose : Primarily aimed at CSS implementers (browser...

The   CSS Working Group   published the   CSS Snapshot 2024   as a Group Note. This document collects together into one definition all the specifications that together form the current state of Cascading Style Sheets (CSS) as of 2024. The primary audience is CSS implementers, not CSS authors, as this definition includes modules by specification stability, not Web browser adoption rate.  When the first CSS specification was published, all of CSS was contained in one document that defined CSS Level 1. CSS Level 2 was defined also by a single, multi-chapter document. However for CSS beyond Level 2, the CSS Working Group chose to adopt a modular approach, where each module defines a part of CSS, rather than to define a single monolithic specification. This breaks the specification into more manageable chunks and allows more immediate, incremental improvement to CSS.  Since different CSS modules are at different levels of stability, the CSS Working Group has cho...
