CSS Selector:
.tcat
The first use of the Category Strips CSS class is to provide the styling for the parts of forum listings that represent a no-posting forum (also known as a category).
Additionally, you will find that the top-most title bar of most tables in vBulletin uses the Category Strips class.
Generally you will use all the available fields when setting values for this class, including the main background color or image, the text color, size and style, and also specific values for any hyperlinks found inside elements using this class.
Example of element using this class:
<table class="tborder" cellspacing="1" cellpadding="6">
<tr>
<td class="tcat">This TD tag uses this class</td>
</tr>
</table>
