HTML, or HyperText Markup Language, is the standard markup language for creating web pages and other information to be displayed in a web browser.
HTML uses a system of tags and attributes to define the structure and content of a web page. For example, a paragraph of text might be enclosed within the "p" tag, while a header might be enclosed within an "h1" tag. The tags and attributes in HTML provide information to the web browser about how to display the page and its contents.
HTML has evolved over time, and the latest version, HTML5, includes new features such as video and audio playback, improved support for mobile devices, and new semantic elements that make it easier to describe the structure of a web page.
