HTML, which stands for HyperText Mark-Up Language, is the language for describing structured documents as well as the language used to create web pages in the Internet.

The language is based on an existing, international formatting standard SGML, Standard Generalized Mark-Up Language, which is used for text processing.

HTML is one of the three main components of the web alongside CSS and JavaScript, that are used to primarily develop web pages and web applications which run on web browsers like Chrome, Firefox, and Internet Explorer. All web applications use HTML because it is the only language which browsers understand and render on the computer screen.
