Vertical Centering with CSS

HTML & CSS

Here is a site that illustrates what I am trying to do.

The content is displayed in the exact center (both horizontally and vertically) no matter what the size of the viewport… even if it is resized after the page loads.

I know that margin: 0 auto would center the content horizontally but what snippet of CSS would center the content vertically without knowing the height of the browser’s viewport?

       function openWindow ( linkURL, windowWidth, windowHeight, haveToolbars, url_for_google ) {
            var width = screen.width;
            var height = screen.height;
            myWindow = window.open( linkURL,'htmluploadWin','toolbar=no,location=no,directories=no,status=no,menubar=yes,scrollbars='+haveToolbars+',resizable=yes,top=0,x=0,y=0,left=0,width='+windowWidth+',height='+windowHeight);
            [COLOR="Red"]if (myWindow) {
                myWindow.moveTo( (width-windowWidth)/2, (height-windowHeight)/2 );
            }[/COLOR]

try w/o js and see what landing page you get to.

Can it be done with CSS alone?
