HTML (HyperText Markup Language) is the standard markup language for creating web pages. HTML5 is the latest major revision of HTML, and it includes a number of new features and improvements over previous versions. HTML files contain text and tags that define the structure and content of a webpage, including headings, paragraphs, lists, images, videos, and links.

HTML5 also provides APIs for offline storage, geolocation, and drag-and-drop functionality, enabling richer and more interactive web applications. HTML files are essential for creating websites and web applications, and they are supported by all major web browsers.
