这在WebKit中已经成。
<html>
<head>
<style>
div { background: -webkit-canvas(squares); width:600px; height:600px; border:2px solid black }
</style>
<script type="application/x-javascript">
function draw(w, h) {
var ctx = document.getCSSCanvasContext("2d", "squares", w, h);
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(300, 300)">
<div></div>
</body>
</html>
当前，Firefox 4包含一项功能，该功能允许您以这种方式将任何元素（包括画布）用作CSS背景：
<p id="myBackground1" style="background: darkorange; color: white; width: 300px; height: 40px;">
This element will be used as a background.
</p>
<p style="background: -moz-element(#myBackground1); padding: 20px 10px; font-weight: bold;">
This @R_734_2419@ uses #myBackground1 as its background!
</p>
