try changing these #bullets{ width: 310px; float: center; position:absolute; margin-left: 0px; margin-top: 10px; } #involved{ width: 310px; float: center; margin-left: 350px; margin-top: 12px; } into these #bullets{ width: 310px; float:left; position:absolute; margin-left: 0px; margin-top: 10px; } #involved{ width: 310px; float: right; margin-left: 350px; margin-top: 12px; } i tested in totalvalidator and it seemed to look right.
Right, cause there's no such thing as float:center and I'm wondering if some browsers are seeing float: and are assuming it's left.
