The W3C CSS-TAG Houdini Task Force repository containing editor drafts of specifications that expose CSS engine internals (Paint API, Layout API, Animation Worklet, Typed OM, Parser API, etc.) to JavaScript. It is a standards-drafting repository rather than runnable software, with issues used for spec discussion.

Use cases

• track the status of CSS Houdini specifications
• read editor drafts for the CSS Painting and Layout APIs
• file or follow specification issues for Houdini APIs
• learn how to extend CSS with worklets and custom properties
• check which Houdini features are ready for browser use
• contribute normative spec changes with web-platform-tests

When to choose

• you are implementing or reviewing browser support for Houdini APIs
• you want authoritative, up-to-date specification text for Houdini modules
• you need to raise or track standards-level issues about CSS extensibility

When to avoid

• you want a library or polyfill to use Houdini APIs in production code
• you need tutorials or end-user documentation rather than normative spec drafts
• you are looking for general CSS documentation unrelated to Houdini
