I have a very similar question about changing the featured categories section. When I try to change the CSS to have 3 of them fall onto the same line, it doesn't react as expected.
When I look through the code, there's a <div class="clear"></div> that seems like is being generated somewhere along the line... also, feat cat 2 is given the class ".right-side" and I can't figure out where... I've looked through the feat-cat2.php and I can't figure out where either the class is being added or where that clear is coming from. (I'm familiar with HTML and CSS but new to PHP)
