The mechanism of Modernizr is to make self-titled JavaScript object containing properties for every feature. If the browsers supports the property, it will evaluate true, if it doesn’t, it will be false.

We would like to underline that this plugin doesn’t add any feature which is not available on browser, but rather detect its native availability. Then it offers you an alternative to use the feature on that browser according to its ability that has been detected before. Now you can try this smart Modernizr by downloading it here.
