Firefox plugin for CSS?

HTML & CSS

Do we have a Firefox plugin for CSS ? for example, when I view the source, I point the mouse in some text, elements … , it will show me which CSS style is using.

Or we have standalone tool to achieve this ?

Thanks.

The closest you’re going to get to a Firebug for IE is the IE Developer Toolbar, not nearly as easy to use or robust by it is helpful.

Install Firebug and the Web Developer toolbar. Will be the best thing you have ever done for your Fox.

I wish there is replica tool of “FireBug” for IE also. DebugBar is still can’t do things on the fly like FireBug. Will make the life much easier for the front end developers.
