When I click on a link I am trying to get a div to enlarge. The div is called "sidebox". The website is www.mediascrubber.com
The div is the white box with the grey line around it.
<li><a href="#!/page_One">One</a><!-- Begin One -->
<div id="sidebox" class="sidebig">
</li><!-- End One -->
I want it to work like www.legalzoom.com
