Quick Search for Modernizr Tests
Modernizr Helper runs all tests quickly on page load to detect browser features, then the results are displayed on the following tables. At this point, it's about two hundred features detects based on stable Modernizr Builder, including most of the non-core detects.
Each table row has a references to: specification, some non-normative tutorial, can-i-use compatibility, and the detector source code.
You can filter the table and then quick access to the detector using hashtag permalink.
