HTML5 is a current version of HTML and it is also called the fifth version of HTML. HTML stands for a hypertext markup language. It is not a programming language but a markup language for creating a webpage and the webpage is run or view on browsers like Chrome, Mozilla, safari, and opera, etc. it is used to interpret and compose text, images, create the link with other webpage and other material into visual or audible web pages. HTML was developed by Tim Berners-Lee in 1990. In 1996, HTML has been maintained by W3C(World Wide Web Consortium). In 2000, HTML became an international standard (ISO/IEC 15445:2000) and after html4.0 was published in 2001. In 2004, I started converting HTML4 to a new version HTML5 with some elegant tag in 2004 by the Web Hypertext Application Technology Working Group (WHATWG).
