In firebug, how do I find out all of the css styles being applied to a particular element?

Question

I'm way buried in many nested levels of css, and I can't tell which style layer/level is messing up my display. How can I find out everything that's being applied to a particular element?

Answer 1

Click Inspect (upper left) to select the element you want to check

then on the right panel select the tab labeled "Style". It will also tell you from which .css file that particular property comes from
