16	* Modernizr is a script that detects native CSS3 and HTML5 features
17	* available in the current UA and provides an object containing all
18	* features with a true/false value, depending on whether the UA has
19	* native support for it or not.
20	*
21	* Modernizr will also add classes to the <html> element of the page,
22	* one for each feature it detects. If the UA supports it, a class
23	* like "cssgradients" will be added. If not, the class name will be
24	* "no-cssgradients". This allows for simple if-conditionals in your
25	* CSS, giving you fine control over the look & feel of your website.
