/*
* Modernizr is a script that will detect native CSS3 and
HTML5 features
* available in the current UA and provide an object containing
all
* features with a true/false value, depending on whether the
UA has
* native support for it or not.
*
* In addition to that, Modernizr will add classes to the <html>
* element of the page, one for each cutting-edge feature. If the
UA
* supports it, a class like "cssgradients" will be added. If not,

* the class name will be "no-cssgradients". This allows for
simple
* if-conditionals in CSS styling, making it easily to have fine
* control over the look and feel of your website.
