The HyperText Markup Language


The HyperText Markup Language (HTML) is the publishing language of the World Wide Web. The first version of HTML was described by Tim Berners-Lee in late 1991. The current W3C Recommendation for HTML is HTML 4.01, published in December 1999. There is however intensive work to define its next version, HTML5.
