Browsers apply default styles to ceratin elements. In this case it's ul that gets some margin. Note that this margin separates the divs even though the divs themselves have no margins.
Even if you don't already use firefox, you should download it along with the firebug plugin. With Firebug you can look at an element in your source code and see the styles that are being applied, the layout (width/height, padding, margin), and even manipulate the styles to view what a change in your CSS would do.
