Answer»

Modernizr is an open source, MIT-licensed JavaScript library that DETECTS SUPPORT for many HTML5 & CSS3 features. You should ALWAYS use the latest version. To use it, include the following highlighted <script> element at the top of your PAGE.

<!DOCTYPE html> <html> <HEAD>  <meta charset="utf-8">  <title>Dive Into HTML5</title>   <script src="modernizr.min.js"></script> </head> <body></body> </html>
