very odd css problem

[Chadi]

This is still not working at all

<style type="text/css">
a.tagcloudlink:link, a.tagcloudlink:visited { text-decoration:none; }
a.tagcloudlink:hover, a.tagcloudlink:active { text-decoration:underline; background-color: #4F57A0; color: white; }
a.level1 { font-size: 11px; color: #ff9900; }
a.level2 { font-size: medium; }
a.level3 { font-size: large; }
a.level4 { font-size: x-large; color: #ff9900; }
a.level5 { font-size: xx-large; }
</style>
