HyperText Markup Language (HTML) is the standard markup language used for creating web pages and web applications. It defines the structure of content, utilizing a system of elements and tags to organize text, images, links, and other multimedia components. HTML does not dictate the appearance of a web page—such functionality is managed by styling languages—but rather provides the underlying semantic framework that dictates what content is and how it is nested. Modern implementations include support for various data types and structural components, allowing for the development of complex, interactive digital documents that can be interpreted and displayed across diverse computing platforms and browsers.
