I asked this on the CSS forum and haven't really gotten much help, even from past threads.

What I'm trying to do is center this page, http://www.xsystem.gr/stylebytes/thanks.html, vertically (not horizontally) so the divs still span the monitor no matter the resolution.

is this possible? I don't have a lot of content on the site, and it would look funny on large resolutions with only 25% of the top part of the screen being used.

this is the relevant CSS, if anyone cares to see:

body{
font-family: Verdana, Arial, Helvetica, sans-serif;
color: #666666;
line-height: 1.166em;
margin: 0px;
padding-top: 0px;
padding-right: 0px;
padding-bottom: 0px;
padding-left: 0px;
}



#masthead{
margin: 0;
width: 100%;
padding-top: 10px;
padding-right: 0px;
padding-bottom: 10px;
padding-left: 0px;
background-image: url
border: medium none #000000;

}

#navBar{
padding: 0px;
