HTML5 is a language for structuring and presenting content for the World Wide Web. it is the fifth revision of the HTML standard (created in 1990 and standardized as HTML4 as of 1997) and as of February 2012 is still under development. Its core aims have been to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices (web browsers, parsers, etc.). It improves interoperability and reduces development costs by making precise rules on how to handle all HTML elements, and how to recover from errors
