The Complete HTML
HTML is the standard markup language used to create web pages. It was created by Tim Berners-Lee in 1990 and includes elements like <head>, <body>, <p>, and <img> to structure and layout web page content. HTML has gone through several versions over the years to support new technologies and is now at version 5, which introduced new semantic elements and embedded media with <video> and <audio> tags. HTML pages are built with tags that do not display but tell browsers how to render content, and attributes provide additional information about elements.

History • In 1980,physicist Tim Berners-Lee, a contractor at CERN, proposed and prototyped ENQUIRE, a system for CERN researchers to use and share documents. • In 1989, Berners-Lee wrote a memo proposing an Internet- based hypertext system.Berners-Lee specified HTML and wrote the browser and server software in late 1990. That year, Berners-Lee and CERN data systems engineer Robert Cailliau collaborated on a joint request for funding, but the project was not formally adopted by CERN. In his personal notes from 1990 he listed "some of the many areas in which hypertext is used" and put an encyclopedia first.

If height and width are not set, the page might flicker while the video loads. • The <source> element allows you to specify alternative video files which the browser may choose from. The browser will use the first recognized format. • The text between the <video> and </video> tags will only be displayed in browsers that do not support the <video> element.
