Fixed positioning, even in IE6

position:fixed.css

html, body { min-height:100%; *height:auto !important; height:100%; }

#foobar { height:100%; width:100%; overflow:hidden; position:fixed; z-index:0; top:0; left:0; }

/* IE6 doesn't recognize position:fixed */

/* http://bit.ly/blamhO */
body { _background-image:url(about:blank); _background-attachment:fixed; }

/* http://bit.ly/aOv4iK */
#foobar { _position:absolute; _top:expression(eval(ignoreMe = document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop)); }
