I\'m trying to center a page and then make it 100%
in height.
I have a div called \"content\" as the parent element of all elements in the HTML page.
What do I need
For centering the page, I typically just put the content div in the center tag, because margin-left/right:auto really doesn't work in all versions of IE.
For making the page the whole height, you can fake it a couple of ways. My favorite is to create a background image for the body tag that is centered horizontally but tiles vertically, so that would give the main div its white background. You probably still have a footer though, so you can position it with bottom:0 and that should keep it at the bottom and give you a content div which appears to extend for the whole page.
