Great test!
Strange thing are these results:
$('test').measure('border'); -> undefined
$('test').measure('border-box-width') -> 210
$('test').measure('width') -> 200
#test {
width:200px;
border:solid 5px #000000;
}
So even with the new measure and getLayout methods in JS Prototype 1.7
you would need to do the math yourself when you just want the border.
Is this a bug?
