Mozilla applications gained support for <canvas> starting with Gecko 1.8 (i.e. Firefox 1.5). The element was originally introduced by Apple for the OS X Dashboard and Safari. Internet Explorer supports <canvas> from version 9 onwards; for earlier versions of IE, a page can effectively add support for <canvas> by including a script from Google's Explorer Canvas project. Google Chrome and Opera 9 also support <canvas>.

The <canvas> element is also used by WebGL to draw hardware-accelerated 3D graphics on web pages.

Example

This is just a simple code snippet which uses the {{domxref("CanvasRenderingContext2D.fillRect()")}} method.

HTML

<canvas id="canvas"></canvas>

JavaScript

var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');

ctx.fillStyle = 'green';
ctx.fillRect(10, 10, 100, 100);

Edit the code below and see your changes update live in the canvas:

{{ EmbedLiveSample('Playable_code', 700, 360) }}
