Inside my loop in front-page.php i want a custom class

like:

<tr class="bb-precedes-sibling bb-follows-sibling bb-child ????"><br />

<td><div class="nest"><a href="http://www.example.com/forum/example">Example</a><br /><small> Examples of examples</small></div></td><br />

<td class="num">99</td><br />

<td class="num">1029</td></p>

<p></tr>

on the place of the questionmarks i would like to have a category id as a class.

so i can customise each category in css

can someone help me out?
