*
* PREFACE:
*
* This box-sizing polyfill is based on previous work done by Erik Arvidsson,
* which he published in 2002 on http://webfx.eae.net/dhtml/boxsizing/boxsizing.html.
*
* USAGE:
*
* Add the behavior/HTC after every `box-sizing: border-box;` that you assign:
*
* box-sizing: border-box;
* *behavior: url(/scripts/boxsizing.htc);`
*
* If you prefix the `behavior` property with a star, like seen above, it will only be seen by
* IE6 & IE7, not by IE8+ (it's a hack) which is better for the performance on those newer browsers.
*
* The URL to the HTC file must be relative to your HTML(!) document, not relative to your CSS.
* That's why I'd advise you to use absolute paths like in the example.
*
