CSS Layout Problem

Hey

Ive been trying to get the basic layout framework for http://www.matthewpscott.com to get working i seem to have the container, navigation and footer working but the content section will not work. Could someone please take a look at it and see whats the matter :D. The content section seems to keep going below the navigation instead of too the right of it like it should? Also how would i go about vertically align the container?.

Basic frame work is

<container>
<navigation>
</navigation>
<content>
</content>
</container>
<footer>
</footer>

Cheers

Matthew
