Resize The Inside Of A Window

This is something that i came up with a while back, but never got around to putting up. when you resize a window, you don't get the same result across different browsers because of different chrome sizes. the way around this, is to resize your window based on the visible document area. this function does that.

this should work in IE4+ and NS4+. i've tested it in IE5+, and Moz 1+

<SCRIPT><!--
self.resizeIn = function(new_w, new_h) {
var old_w = self.innerWidth || document.body.offsetWidth;
var old_h = self.innerHeight || document.body.offsetHeight;
if (!new_w) { new_w = old_w; }
if (!new_h) { new_h = old_h; }
new_w -= old_w; new_h -= old_h;

self.resizeBy(new_w,new_h);
}
//--></SCRIPT>
