Implementing this proposal would break existing functionality, where CSS is currently used to style parts outside the #content or where CSS is dependent on selectors including elements above the #content.
Examples (perhaps these examples below could or even should be rewritten in a better way, but who is going to do so across all existing wikis?):
- la:MediaWiki:Vector.css (styling #p-lang in order to show {{Link FA}} stars)
- la:MediaWiki:Common.css (styling #p-lang in order to show {{Link FA}} stars)
- la:MediaWiki:Gadget-vultus-smallcaps.css (selector above #content)
