Tests the styles found in reset.css. First up...
Changes the box model. Could be a risky strategy...
It says at Quirksmode that box-sizing doesn't work with min- or max-width or height. Here, it seems to work in all but IE8, with just a couple of gotchas in FF.
FF: if width or height are 'auto', min-height and max-height are set on the content-box.
IE8: min- or max- width or height are always applied to the content-box.
