Introduction to HTML5

INTRODUCTION TO HTML5

HTML5 is the next major revision of the HTML standard. Like its immediate predecessors, HTML 4.01 and XHTML 1.1, HTML5 is a standard for structuring and presenting content on the World Wide Web. HTML5 is a response to the observation that the HTML and XHTML in common use on the World Wide Web is a mixture of features introduced by various specifications, along with those introduced by software products such as web browsers, those established by common practice, together with many syntax errors in existing web documents. It is also an attempt to define a single markup language that can be written in either HTML or XHTML syntax. It includes detailed processing models to encourage more inter-operable implementations; it extends, improves and rationalizes the markup available for documents, and introduces markup and APIs for complex web applications.

BACKWARD COMPATIBILITY WITH HTML4

There is no need to throw away your existing markup. All application working on HTML4 will work on HTML5. HTML5 supports all the form controls from HTML 4, but it also includes new input controls. Some of these are long-overdue additions like sliders and date pickers; others are more subtle. For example, the email input type looks just like a text box, but mobile browsers will customize their onscreen keyboard to make it easier to type email addresses. Older browsers that don’t support the email input type will treat it as a regular text field, and the form still works with no markup changes or scripting hacks.

Support for HTML5

Most of the new features of HTML5 are well supported by common browsers like Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Mobile Browsers etc.
