background-repeat: no-repeat;
background: rgb(30,87,153); /* Old browsers */

position:absolute; bottom:0px; right:0px;

background-size:40% 180%;
-moz-background-size:63px 130px; /* 老版本的 Firefox */
background-repeat:repeat;
padding-bottom:1%;
margin:0;
}
</style>
</head>
<body>
<div>
<p></p>
<p>rtyeryteryteryteryt</p>
<p>rtyeryt</p>
<p>ertyerytre</p>
<p>ertyerytre</p>
<p>ertyerytre</p>
<p>ertyerytre</p>
<p>ertyerytre</p>

</div>
<div id="body_foot1" style="position:absolute;bottom:1px;height:20%; width:100%; ">
<div id="body_foot" style="position:absolute;bottom:1px;height:100%; width:100%; ">
</div>
</div>
</div>
</div>
</body>
</html>

其中主要有：
1、渐变背景的的设定：body{}
2、动态在低端的白云：设定了body_foot1和body_foot1中的循环图片显示定义，以及div动态底端的设定。以及嵌套div掩盖白云图片规律性显示。
