Stretch and scale CSS background

Question

Is there a way to get a background in CSS to stretch or scale to fill its container?

Answer 1

An additional tip for SolidSmile's cheat is to scale (the proportionate re-sizing) by setting a width and using auto for height.

Ex:

#background {
    width: 500px;
    height: auto;
    position: absolute; 
    left: 0px; 
    top: 0px; 
    z-index: 0;
}
