How to make my site on the center of the screen

Or even shortcut it down to:

Code:

#webcomtain {
    width: 960px;
    background-color: white;
    margin: 0 auto;
}

Note: try using 960px as the width for 1024x768 screens - just a tad more usuable as its divisible by 3, 4, 5, 6, 8, 10, 12, 15, and 16 (think grid)

Oh I love my css!
