 A CSS 3D slideshow tool for quickly creating good looking HTML presentations. Doesn't _rely_ on any external libraries but [highlight.js](http://softwaremaniacs.org/soft/highlight/en/description/) is included by default for code highlighting.
 
-Note that this requires a browser with support for CSS 3D transforms and ``classList``. If CSS 3D support is not detected, the presentation will degrade to less exciting 2D transitions. A [classList polyfill](https://github.com/remy/polyfills/blob/master/classList.js) from [@remy](https://github.com/remy) is also incuded to make this work in < iOS 5, < Safari 5.1 and IE.

 Curious about how it looks in action? [Check out the demo page](http://lab.hakim.se/reveal-js/).
