What is HTML?
When using a web browser like Google Chrome or Mozilla Firefox, you request an HTML document from a web server, and the web browser rends a web page for you to view. On that web page are links that you click, and they request then render other HTML documents from the server.
History of HTML
HTML first appeared in the early 1990s. In 1990, Tim Berners-Lee, a contractor for CERN and computer scientist, specified HTML while writing browser and server software. In 1991, Berners-Lee published a document called HTML Tags, which outlined the eighteen elements that made up HTML at the time. In an early request for funding to further develop HTML, Berners-Lee cited an encyclopedia as a practical application of the technology.
There have been five versions of HTML since its original inception. December 14, 2017, marked the publishing of HTML 5.2 as a W3C Recommendation. The W3C is the World Wide Web Consortium, a team that develops standards for the World Wide Web.
