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

Add a background-attachment line:

#background {
    background-attachment:fixed;
    width: 100%; 
    height: 100%; 
    position: absolute; 
    margin-left: 0px; 
    margin-top: 0px; 
    z-index: 0;
}

.stretch {
    width:100%;
    height:auto;
}
