- In 2004, the editor of the HTML5 spec, Ian Hickson, mined 1 billion web pages via the Google index, looking to see what the “real” web is made of. One of the analyses he subsequentlypublished (http://code.google.com/webstats/2005-12/classes.html) was a list of the most popular class names in those HTML documents. More recently, in 2009 the Opera MAMA crawler (see http://devfiles.myopera.com/articles/572/idlist-url.htm) looked againat class attributes in 2,148,723 randomly chosen URLs and alsoids given to elements (which the Google dataset didn’t include) in 1,806,424 URLs.
- Embed: is used to embed plugin … HTML 5 supposed to replace all the plugin but not over nightKeyGen: where you form need to send a public KeyProgress: is used to represent a progress meter to indicate the completion of a task

- Geolocation: W3C, not HTML5, API that works with maps, mobile phones can locate you on the mapMessages: allow you to send message from one domain to anotherWeb workers: Threads, is a way of running a discrete block of JavaScript in a background process to the main browser.Web Sockets: is not HTML 5, -Comet- Web Sockets give you a bi-directional connection between your server and the client, the browser. This connection is also real-time and is permanently open until explicitly closed. This means that when the server wants to send your client something, that message is pushed to your browser immediately.
- HTML5 is a good fit; HTML is human readable, and there are over ten million web developers (compared to much fewer native and plug-in developers).
- HTML5 is a good fit; with HTML web-based mobile applications, your application consistently displays across mobile web browsers, including future devices.
- HTML5 is a good fit; with HTML web-based mobile applications, you don’t even need the approval of a app store to reach your audience.
