HTML5 UI Elements

HTML 5 is a set of rich browser capabilities, including local storage, enhanced forms and canvas support, standard video and audio, geolocation, and plenty more. It is a standard being worked on by the W3C. Some browsers that support HTML5:

• iPhone (Safari)
• Android (Chrome/Chromium)
• WebOS
• Opera Mobile (not Opera Mini)
• Firefox for Mobile (coming soon!)

Note that not all browsers support all HTML5 capabilities, and that you will need to tailor your web app to detect these capabilities and adjust usage accordingly. Modernizr is a javascript library that helps with capability detection and tailoring of your web app to browser capabilities.
