HTML stands for HyperText Markup Language ("markup language hypertext"), refers to the markup language for web development. It is a standard that serves as a reference for the development of websites in different versions, defines a basic structure and code (called HTML) to define the content of a website, such as text, images, and more. It is a standard by the W3C, an organization dedicated to the standardization of almost all web-related technologies, especially about their writing and interpretation. A web browser can read HTML files and compose them into visible or audible web pages. The browser does not display the HTML tags, but uses them to interpret the content of the page. HTML describes the structure of a semantic web site along with the signals for the presentation, so it is a markup language rather than a programming language.
