Solution

You need to specifically set margin and padding to 0 on the "body" element.

just try this in your css:

body { margin: 0; padding: 0; }

Try using firebug, dragonfly or similar to see which element is having padding or margin. For internet explorer (some version, I think) the html element may also have margin/padding.

Is the margin to the left of the ul? in that case it might be because of the automatic indentation of li's. try to fiddle with the CSS-property "list-style-position". But really, an demo on JSfiddler would let me solve it in notime.
