Fixed full page bg image

[evan]

I would like to design a page that is in a container on top of a large background image or pattern.

I would like the background to NOT move while the main content is scrollable.

How is this done?

OK, found it myself -for some reason I thought it was more complicated.

body
{
background-image:url('smiley.gif');
background-repeat:no-repeat;
background-attachment:fixed;
}
