在一个页面中编写css代码，实现下面的功能：

让一个div的背景色在IE6中显示成红色，在IE7中显示成蓝色，IE8中显示成绿色？

如何实现？请告知！分不够，可以加分！

刚才没说完。同理ie7就是if IE 7，IE8就是if IE 8。IE和版本号之间有空格。然后在代码段里引入css样式表。样式表里就加个background-color:对应的颜色就可以了

如何判断是ie6，ie7，ie8呢?

<html>	<head>		<title></title>		<meta http-equiv="Content-sytle" content="text/html;charset=utf-8" />		<!-- 如果是ie6,那么加入ie6的样式表 -->		<!--[ if IE 6]>			<link rel="stylesheet" type="text/css" href="ie6.css" />		<![endif]-->		<!-- 同理ie7,ie8 -->		<!--[ if IE 7]>			<link rel="stylesheet" type="text/css" href="ie6.css" />		<![endif]-->		<!--[ if IE 8]>			<link rel="stylesheet" type="text/css" href="ie6.css" />		<![endif]-->		<!-- 另外if gt IE 8表示IE版本大于8.gte是小于等于.lt是小于 -->	</head>	<body>	</body></html>

可以给出一个完整的例子吗？再加你分

demo.htm用来显示效果。

<!DOCTYPE html><html>	<head>		<title>demo</title>        <meta http-equiv="Content-sytle" content="text/html;charset=utf-8" />        <style type="text/css">        	div {         		color:white;        	}        </style>        <!--[if IE 6]>            <link rel="stylesheet" type="text/css" href="ie6.css" />        <![endif]-->        <!--[if IE 7]>            <link rel="stylesheet" type="text/css" href="ie7.css" />        <![endif]-->        <!--[if IE 8]>            <link rel="stylesheet" type="text/css" href="ie8.css" />        <![endif]-->	</head>	<body>		<div>			<p>this is a box.It will be red in ie6,blue in ie7,green in ie8.</p>		</div>	</body></html>
