Q about a non moving background, how do u get the background to stay still??? Options

[ComanderCC]

U know those really cool backgrounds that don't move, no matter how much u scroll on the page? The text and other content do, but the background dosn't. Well, I'd really like that for my site, but I can't figure out how to do it. Can it be done with html or css? I know some html, and I just learned the basics in css, but I don't know javascript, so if it's posible not to use it, I'd rather not. I tried to get a url of a site that does this, but I can only find it on myspace, and u have to be added as a friend to see it and all that. I'm sure someone knows what I'm talking about. Also, as long as I'm here, what's the preportions for a background image that will fit nice in any screen? thanx,
Dominic
