"HTML" stands for "HyperText Markup Language" and is the standard language used for creating web pages and applications. HTML provides the structure of a webpage by using elements such as headings, paragraphs, links, and images, enabling browsers to render content correctly. It also incorporates attributes that define the appearance and behavior of web components. HTML is often used in conjunction with other technologies, such as CSS for styling and JavaScript for interactivity, forming the foundation of web development.
