Dynamcially adding style

Dynamically add style to a page...

var style = "body{color:#666;}";
var s = document.createElement('style');
s.setAttribute("type", "text/css");
if (s.styleSheet) {   // IE
    s.styleSheet.cssText = style;
} else {
    var stxt = document.createTextNode(style);
    s.appendChild( stxt );
}
document.getElementsByTagName('head')[0].appendChild(s);

Remember to minify the style text using something like http://refresh-sf.com/yui/
