Thread:Talk:Requests for comment/Scoping site CSS/De-scoping the proposal/reply (2)

That sounds like a good idea and good first step. Separating ui styling changes from article styling into MediaWiki:Ui.css would be a useful distinction and would allow the scoping of Common.css

To help with adoption we could imagine making this an opt in thing to allow time to move relevant styles from MediaWiki:Common.css
