Question
I'm wondering if this is possible with CSS. I want my background image to begin from an absolute center alignment and tile repeat outwards from there.

OTHER TIPS
You can use background-position property to center the background and set the repeat value to background, background: url('yourimage') repeat;
#pattern{
background: url('pattern.jpg') center center;
