HTML, which stands for HyperText Markup Language, is the standard language used to create and structure web pages. It defines the layout and organization of content on the internet, allowing developers to display text, images, videos, links, and interactive elements within a browser. Rather than being a programming language, HTML is a markup language that uses tags to label and format content.

HTML is at the heart of all web development. It provides the foundation upon which every website is built. While CSS is used to style the content and JavaScript is used to make it interactive, it is HTML that forms the structure. Without HTML, browsers would have no idea how to interpret and present content in a readable and organized way.
