Modernizr is an open-source, BSD-MIT dual-licensed JavaScript toolkit that detects available features in browsers. It originally focused on CSS3-specific features with only a couple HTML5 features detected, but grew out to become “the HTML5 detection library” as more and more new features were added that related to HTML5.

Modernizr is currently at version 1.5 and can be downloaded from the official site. The next major release, 2.0, is slated to feature a modular approach, allowing users to pick and choose which tests they want included before downloading the toolkit.
