Standard HTML lists have a certain amount of left-indentation. The amount varies on each browser. Some browsers use padding (Mozilla, Netscape, Safari) and others use margins (Internet Explorer, Opera) to set the amount of indentation.
To remove this left-indentation consistently across all browsers, set both padding and margins to "0" for the "UL".
