This is the currently template I'm working on (don't click on any of the menu links as they will take you to a current template).

www.littlemissnc.com/index-build3.php

In the sitestyle.css, I'm using #wrapper3, #header3, #main3 and #footer3

My screen's resolution is the 1024x768 and the site centers fine in IE8 and FireFox 3.6.17

My husband's computer monitor is a touch wider than mine and he has his resolution set much higher. The website does NOT center in Firefox, IE, nor Chrome.

And someone I'm working with on this site is on a Mac using the Safari browser and the site does NOT center for him.

Are there special hacks I need to be placing in my CSS?
