list style is played in different browsers. the best way to do this is
ul#div-menu li { background: url(/images/seperator.gif) no repeat 0 0; }
the first-child class pseudo-class does not work in all browsers, so you can apply the "first" class to the first li and set the background to none
ul#div-menu .first { background: none; }
: , . , ( 0). x, - y. 2px 2px
ul#div-menu li { background: url(/images/seperator.gif) no repeat 2px -2px; }
