This script allows you to apply different class values to an HTML element based on its width. Use it as follows:
<div data-squery="min-width:400px=wide max-width:10em=small"> <p>Content here</p> </div>
This will apply a class of
wide when the element is wider than 400 pixels and a class of
small when it is narrower than 10 ems. It works in all modern browsers back to and including IE6.
