<canvas> is an HTML element which can be used to draw graphics using scripting (usually JavaScript ). It can, for instance, be used to draw graphs, make photo compositions or do simple (and not so simple ) animations. The image on the right shows some examples of <canvas> implementations which we will see later in this tutorial. <canvas> was first introduced by Apple for the Mac OS X Dashboard and later implemented in Safari and Google Chrome. Gecko 1.8-based browsers, such as Firefox 1.5, also support this element. The <canvas> element is part of the WhatWG Web applications 1.0 specification also known as HTML5.
Abstract HTML is the core language of the World Wide Web. The W3C publishes HTML5, which is the fifth major revision of HTML. The WHATWG publishes HTML, which is a rough superset of HTML5. "HTML5 differences from HTML4" describes the differences of these documents from HTML4, and calls out cases where HTML is different from HTML5.
