HTML 5 in 5 minutes

HTML 5 is quite a hot topic at the moment, with good reason. HTML 5 is the first major update to HTML in over a decade. XHTML did teach us a lot of good disciplines which should be followed when developing with HTML 5. HTML 5 includes new APIs and features to reflect the modern browsing experience such as:

• video/audio – without plugins,
• geolocation – pin point and share your location,
• web sockets – threaded processing to reduce browser hangs,
• WebGL – like openGL and DirectX for the browser – game creation,
• BitMap (canvas)/vector (SVG) image creation -  on the fly graphics,
• Better page structure elements – Section, Article, Nav element – this is more for developers
• Backwards compatible and forgiving (XHTML 2 did not want to support this)
