HTML5 is the next generation of HTML that will be the new standard, as the previous version was released in 1999. HTML5 is still a work in progress but is supported by most modern browsers. HTML5 was a cooperation between the W3C and WHATWG to create a new version that reduces the need for plugins, has better error handling, and includes new elements and APIs. Some of HTML5's new features include canvas drawing, video and audio playback, offline storage, and new form controls.
