See what makes Modernizr so popular in this short course by Ryan Seddon.
Modernizr is a feature detection JavaScript library, it works by running tests to see what CSS, HTML and JavaScript features are currently supported by your browser. If your feature isn’t supported then Modernizr will work magic to have it supported. In this course Ryan will get you up to speed with the latest Modernizr 3 by creating custom builds, utilising the CSS class and taking advantage of Modernizr in your JavaScript.
