This mirror is no longer used

This used to be a mirror that updated and built the CSS Working Group's Editor Draft specifications, as a stopgap measure since the canonical server for the Editor Drafts ( was regularly down. However, since September 2022 the setup for this mirror is being used for a new semi-official mirror at Please go there instead.

This site is still used to test changes to the mirror setup in the andreubotella/csswg-auto-build GitHub repo, and you can check out that build output in But all links to the specs now redirect to the mirror.

TLDR: Go to instead. Thanks!
