Answer 1

CSS? Not so much it’s pretty tight, but on older (like gen 4) browsers I’ve seen problems with:

• doing too much on the * selector
• using inherit a lot
• using the IE expression value abusively
• loading a lot of external resources (images, other CSS docs)
• applying a lot of what you might call unanchored selectors like div div

Basically anything which would be difficult to cascade through or would cascade a lot.
