Html5 cross browser polyfills - Modernizr - GitHub github.com · Originally posted on Pinboard

So here we're collecting all the shims, fallbacks, and polyfills in order to supplant html5 functionality in browsers that don't natively support them. The general idea is that: we, as developers, should be able to develop with the HTML5 apis, and scripts can create the methods and objects that should exist. Developing in this future-proof way means as users upgrade, your code doesn't have to change but users will move to the better, native experience cleanly.
