This section documents problems found in the CSS specs and working drafts. Problems documented here will be addressed by the editors, possibly after discussion in a CSS Working Group meeting, and will result in changes, corrections, clarifications, or no change.

The group uses github for issue tracking, in csswg-drafts, fxtf-drafts, css-houdini-drafts, but some old issues are stored in Bugzilla or Tracker.
