JHtml::_(\'behavior.framework\', true);
//if(!$templateparams->get(\'html5\', 0)):

background-repeat:repeat;
padding-bottom:1%;
margin:0;
}
#body_foot1

</style>
</head>
<body>
<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。
