My neopets lookup works fine with IE but when I look at it on Firefox, my closing code that sets up the table for my stats isn't working. Look here: http://www.neopets.com/randomfriend.phtml?user=layneaa or here is my closing code:
<style>
b.1{width:530;border:4px ridge #FF0000;background-color: white; font-color: red; position:absolute;top:770;left:130;width:530;heigh t:205px;overflow:auto;}
.sf{display: none;}</style>
<b class="1">

How can I make it work with all browsers?

You can't make it work with all browsers.
