HTML5 Canvas 将在HTML5游戏中扮演重要角色。
第一个例子：
<html>
<head>
<script type="application/x-javascript">
function draw() {
var canvas = document.getElementById("canvas");
if (canvas.getContext) {
var ctx = canvas.getContext("2d");
ctx.fillStyle = "rgb(200,0,0)";
ctx.fillRect (10, 10, 55, 50);
ctx.fillStyle = "rgba(0, 0, 200, 0.5)";
ctx.fillRect (30, 30, 55, 50);
}
}
</script>
</head>
<body onload="draw();">
<canvas id="canvas" width="150" height="150">
<p>This example requires a browser that supports the
<a href="http://www.w3.org/html/wg/html5/">HTML5</a>
<canvas> feature.</p>
