CSS3-KeyFrames

使一个div元素逐渐移动200像素:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"> 
<title>菜鸟教程(runoob.com)</title> 
<style> 
div
{
	width:100px;
	height:100px;
	background:red;
	position:relative;
	animation:mymove 5s infinite;
	-webkit-animation:mymove 5s infinite; /* Safari and Chrome */
}

@keyframes mymove
{
	from {top:0px;}
	to {top:200px;}
}

@-webkit-keyframes mymove /* Safari and Chrome */
{
	from {top:0px;}
	to {top:200px;}
}
</style>
</head>
<body>

<p><strong>注意:</strong>  @keyframes 规则 不兼容 IE 9 以及更早版本的浏览器.</p>

<div></div>

</body>
</html>
