HTML5 is the major new version of HTML and enables audio and video to play natively in the browser without requiring proprietary plug-ins. Using HTML5, a web app looks and behaves like native iPhone and iPad applications, and using HTML5′s Offline Application Cache, your web applications work even when the device is offline.
