Hello, first you need to fix you theme's index.php you are missing a closing div after the menu, which makes your content load in the menu, then you have an empty div in there as well, it should look something like this:
< body class='section-<%section_id%>'>
< div id='menu'>
< div class='container'>
< %obj_itop%>
< plug:front_index />
< %obj_ibot%>
< /div>
< /div>
< div id='content'>
< div class='container'>
< !-- text and image -->
< plug:front_exhibit />
< !-- end text and image -->
< /div>
< /div>
Then you need to get delete these from #menu in your .css file:
top: 5 0;
bottom: 0;
left: 0;
position: inherit;
and add to #menu a float:left, and change the width to 225px
