Box Model, floats, margin collapsing, margin doubling and MSIE5 Win shrink wrapping…

Box Model
Just in case you’re wondering what the hack is wrong with the Box Model, let me remind you that IE5 Win does not apply borders and padding the way other browsers do. A “good” browser adds border and padding to the width/height of the box while IE5 Win - a bad browser - does exactly the opposite; it subtracts border and padding values from the box itself. And this is ugly.
