parent or chiled css disappears
Sample page here:
http://learntango.webfactional.com/video/35863752#section=comment

Simplified css:

    #video #video_content h3 {
        margin-bottom: 1em; }
    
    #video #video_content {
        position: relative;
        margin: auto;
        width: 640px; }

Simplied html:

    <body id="video">
    <div id="video_content">
    	<h3>My Video</h3>
    </div>
    </body>

Problem:

Only the css block which is last is applied.  I would expect both to be applied.  Can someone please explain this behavior?

Thanks!
David
