RegEx for CSS

I've spent a good amount of time on code refactoring over a large code base.

Maybe for the future I will code up a RegEx generator to help search for all (or obvious) occurances of CSS patterns.  For now, I will just start posting helpful RegEx here: 

For instance, doing a code review, and I'm trying to find all occurrences of this rule (below) in our JSP code base, which is huge. 

#error .moduleStructContent .errorHeader {float:none}
