/* polyfill to use Foundation 3 grid with IE7 */
/*
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.

Please make sure to check your server configuration and update it to use the correct content-type if needed. You can do this in a .htaccess file:
    AddType text/x-component .htc
