Centering html template

I have a 5 page website that I need to be centered in the middle of the browser. It sounds simple but I cant figure it out. Right now the site is completely finished except being left justified and I need it to be in the center when it comes up in case their resolution is small. The project will require making sure all 5 pages are cross browser compatible and centered in common browsers. You just need CSS and html experience.

Thanks
