Ok, it seems to be allowing the css class now... but it won't allow the hover css. Here is what the css looks like...

.mod { color: red; text-decoration: underline; }

.mod a:link, .mod a:visited, .mod a:active { color: red; text-decoration: underline; }

.mod a:hover { color: white; text-decoration: none; }

... and here is the markup...
<span class="mod"> </span>

why no hover effect?

**********************************
I figured it out myself.

Its supposed to be a:hover BEFORE .mod ...like this---> a:hover .mod { color: white; text-decoration: none; }
