HTML, which stands for HyperText Markup Language, is the backbone of the World Wide Web. It serves as the foundation for creating web pages by defining the structure and content of a document. HTML allows developers to organize information in a hierarchical manner, making it accessible and understandable to both browsers and users.

HTML is a markup language used to create and structure web documents. It consists of a series of elements, each surrounded by opening and closing tags, which define the different parts of a web page. These elements are interpreted by web browsers to render content such as text, images, links, and multimedia.
