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.
