Presentation: Polyfilling The HTML5 Gaps With JavaScript

Track: Taming HTML5 & JavaScript / Time: Thursday 15:20 - 16:20 / Location: St. James

We all want to use HTML5 and the hot new features being implemented in our favorite browsers right away, but how can we use these awesome new capabilities while ensuring older browsers (like our friends IE6, 7 and 8) still render pages and features as expected?

Pollyfills are here to help. Polyfills are JavaScript shims that replicate the standard API found in native features of new browsers for those without such features and in this talk you'll learn how to both use specially written JavaScript to emulate HTML5 features and even pick up pro-tips about writing your own polyfills along the way
