Here I was blissfully setting up a couple of Firebug screenshots and you guys were hard at work
I’ll toss them in anyway, of course.
The first are the three steps to target a box using Firebug.
And the second is an example of what one might see while hovering over one of the tags… in this case, the <div id="logoimg">
tag, The medium blue is the box, purple is padding, yellow is margin. I also clicked the tag so I could see the CSS in the right panel.
