HTML 5 reduces development costs by making precise rules on how to handle all HTML elements, and how to recover from errors. HTML5 is being developed as the next major revision of HTML (HyperText Markup Language), the core markup language of the World Wide Web. HTML 5 is a new version of HTML and XHTML. The HTML5 draft specification defines a single language that can be written in HTML and XML. It aims to reduce the need for proprietary plug-in-based rich internet application (RIA) technologies such as Flash, Silverlight, Pivot, and Sun JavaFX. Here is a list of some of the newly introduced tags in HTML 5.
