I'm working on vBulletin theme, but on thread list, every thread has 100% for its width but threads are also bigger than their parents, but when i remove border of threads, they will fit parent's div:). so think this problem is on borders.

You can see that better on jsfiddle (thread is white shape with black border) 

<body>
   <div class="after-body">
        <div class="body-wrapper">
             <div class="threadlist">
                    <ol class="threads">
                        <li class="threadbit"><div class="thread"></div></li>
                        <li class="threadbit"><div class="thread"></div></li>
                    </ol>
             </div>
        </div>
   </div>
</body>
