(The next generation of HTML)

Brief about html5:

In order to bring a bullish hike in the world of internet and browsing the World Wide Web in cooperation with the Web Hypertext Application Technology Working Group (WHATWG) is here geared up with the new generation language HTML5, the fifth revision of HTML, It not only structures but also presents content for the world wide web much more efficiently and effectively as compared to previous versions of HTML. It also outshines XHTML1 and DOM2HTML. It is a core technology in the internet proposed by Opera Software. It is designed to bring consistent understanding between the browser and the machine i.e. a language that is easily readable to the user and understood by the machine (computer,browser,parsers etc.). It is also an attempt to define a single markup language that can be written in either HTML or XHTML syntax. To encourage more interoperable implementations it includes detailed processing models; it extends, improves and rationalizes the markup available for documents, and introduces markup and application programming interfaces (APIs) for complex web applications.

New attributes have been introduced in HTML5, while some elements and attributes have been removed. Some elements, such as <a>, <cite> and <menu> have been changed or revised. The APIs and document object model (DOM) are no longer in use, but play important parts of the HTML5 specification.HTML5 also provide the feature of error correction so that user deals with only correct syntax.

Some of the new elements or attributes included in HTML5 are semantic replacements for common uses of generic block (<div>) and inline (<span>) elements, for example <nav> (website navigation block), <footer> (usually referring to bottom of web page or to last lines of HTML code), or <audio> and <video> instead of <object>. Some elements such as <font> and <center> have been removed as these effects are achieved using Cascading Style Sheets. It also focuses on the importance of DOM scripting (e.g., JavaScript) in Web behavior. The HTML5 syntax is no longer based on SGML despite the similarity of its markup. HTML5 also includes Web Forms 2.0, a previously separate WHATWG specification.

LOOKING AT THE FEATURES PROVIDED BY HTML5
