HTML5

This document provides an overview of HTML5 and what's new in the latest version. It discusses new semantic elements like <header>, <nav>, and <article> that improve document outlining. It also covers new multimedia features like native audio and video playback without Flash, as well as 2D/3D graphics using <canvas>. Other additions include new form controls, multiple file uploading, and geolocation. While HTML5 brings many new features, it is an ongoing evolution of HTML rather than a completely new language.
