How hard is it to do something like this?

[Phaser]

I like the layout/look of the following site:

http://aceh.mercycorps.org/

It uses Mambo, however i'd like to create something similar using html/css.

How would I get the content section to extend depending on the size of the content in there? Just use a div with no max height setting?

And to keep the navigation in the same place I guess i'd use a absoloute div?

Cheers for the help.

How would I get the drop down buttons sorted?

No experience with drop down menus at all.
