1. HTML5 − OVERVIEW HTML5
HTML5 is the next major revision of the HTML standard superseding HTML 4.01, XHTML 1.0,
and XHTML 1.1. HTML5 is a standard for structuring and presenting content on the World
Wide Web.
HTML5 is a cooperation between the World Wide Web Consortium (W3C) and the Web
Hypertext Application Technology Working Group (WHATWG).
The new standard incorporates features like video playback and drag-and-drop that have
been previously dependent on third-party browser plug-ins such as Adobe Flash, Microsoft
Silverlight, and Google Gears.
Browser Support
The latest versions of Apple Safari, Google Chrome, Mozilla Firefox, and Opera all support
many HTML5 features and Internet Explorer 9.0 will also have support for some HTML5
functionality.
The mobile web browsers that come pre-installed on iPhones, iPads, and Android phones all
have excellent support for HTML5.
New Features
HTML5 introduces a number of new elements and attributes that can help you in building
modern websites. Here is a set of some of the most prominent features introduced in HTML5.
New Semantic Elements: These are like <header>, <footer>, and <section>.
Forms 2.0: Improvements to HTML web forms where new attributes have been
introduced for <input> tag.
Persistent Local Storage: To achieve without resorting to third-party plugins.
WebSocket : A next-generation bidirectional communication technology for web
applications.
Server-Sent Events: HTML5 introduces events which flow from web server to the
web browsers and they are called Server-Sent Events (SSE).
Canvas: This supports a two-dimensional drawing surface that you can program with
JavaScript.
Audio & Video: You can embed audio or video on your webpages without resorting
to third-party plugins.
