What tools did you have to use for debugging CSS?

[Damian Demasi]

What I usually do is this:

*, *:before, *:after {
    outline: 1px dashed blue; /* Debugging purposes */
}

This will render a dashed blue line on all elements, so I can see their position and sizes.

The other tool I use is just the Chrome Developer Tools.
