Hi jedd,
I can design you up a layout like this one that CodeIgniter uses if you would like.
You have to keep in mind that it will have to support backwards compatiblity.
you only need to support IE7 and down, most of the new browsers support CSS 2.1
een IE8.
I also have theme switching code in javascript that does it on the fly.
I did start last night converting my auth code over to CodeIgniter.
The nice thing about my code is that it tracks users, guests and banned users.
Enjoy
