Overview

HTML5 (HyperText Markup Language, version 5) is the fifth major revision of HTML, the core markup language of the World Wide Web. Standardized by the W3C and WHATWG, it was officially released in October 2014.

HTML5 introduces semantic elements (like `<nav>`, `<footer>`, `<article>`), multimedia support (native `<audio>` and `<video>` tags), canvas for 2D/3D graphics, improved form validation, and new APIs for offline work, geolocation, storage, and WebSockets. It represents a significant evolution from HTML4/XHTML, removing obsolete tags and adding features that reflect modern web development practices.
