By the way… I don’t suppose you are on a Mac… but if you are… CSSEdit is far better than Firebug for inspecting and creating CSS. It’s actually a full-blown editor but with Firebug style “inspectors” and “x-ray” views. I couldn’t live without it. It’s almost worth switching for if you’re a web guy working on PC!! I love it.
Firebug is very useful though. Great utility.
