For this tutorial, we will use a rollover navigation system. To do this we will use a series of descendant selectors - starting with the <ul>. First off, we have to remove the HTML list bullets by setting the "list-style-type" to "none".
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, the best method is to set both padding and margins to "0" for the <ul>.
