This is the repository containing the CSS/TAG Houdini Task Force specifications.

In addition to this git repository, a Mercurial mirror is maintained at https://hg.css-houdini.org/drafts, if for whatever reason you prefer Mercurial.

Specification issues are raised and discussed in GitHub Issues in this repository.

We also maintain the public-houdini mailing list for general-interest topics.

New specifications are generally first incubated in the WICG, in particular:

• Animation Worklet

For normative changes, a corresponding web-platform-tests PR is highly appreciated. Typically, both PRs will be merged at the same time. Note that a test change that contradicts the spec should not be merged before the corresponding spec change. If testing is not practical, please explain why and if appropriate file an issue to follow up later. Add the type:untestable or type:missing-coverage label as appropriate.
