Html5 Overview
3 likes547 views
This document provides an overview of HTML5, including its history, timeline, new features, and compatibility with browsers. Some key points: - HTML5 development is led by the WHATWG and W3C to standardize web applications. It simplifies HTML and introduces new semantic elements like <article>, <aside>, <header>. - New features include multimedia with <audio> and <video> tags, 3D graphics with Canvas, and offline/storage APIs. Forms are enhanced with new input types. - CSS3 adds animation, transitions and transforms. Performance improves with Web Workers and XMLHttpRequest Level 2. - Browser support for HTML5 features is tracked on http://caniuse
