<p><b>注意：</b>Internet Explorer 9 及更早 IE 版本不支持 CSS 动画。</p>

<p>逐步改变 "myBox" 的 z-index 属性 从 1 到 5:<p>
<div id="container">
  <div id="myBox">myBox</div>
  <div style="top:20px;left:20px;z-index:1;">z-index 1</div>
  <div style="top:40px;left:40px;z-index:2;">z-index 2</div>
  <div style="top:60px;left:60px;z-index:3;">z-index 3</div>				
  <div style="top:80px;left:80px;z-index:4;">z-index 4</div>
