HELP!!!! Simple Text CSS problem HELP!!!!!

[SOUL HACK]

Can somebody please tell me where do I go to edit the css styles sheet for the vbulletin.

Cuz, I have a html header and the text is too big. I noticed that it comes from a script thats in the default coding. When I try to remove the script it messes up the whole forum design... So, if someone can just tell me where I can go to edit the css that the script refers to, I can manage the rest myself. Thanks.

This is the script that responsible:
<!-- CSS Stylesheet -->
$style[css]
<if condition="is_browser('opera') AND !is_browser('opera', '8.0.1')">
<style type="text/css" id="vbulletin_opera8fix_css">
ul, ol { padding-$stylevar[left]:20px; }
</style>
