不知道为什么，给div里面的文字设置超链接，但就是点不过去
这是CSS代码：

#container {	margin:0 auto; 	width:1200px;	    }#header { height:110px; background:#87CEEB;filter:alpha(opacity=50);  -moz-opacity:0.5;  -khtml-opacity: 0.5;  opacity: 0.5; }#menu { height:30px; background:#09c;filter:alpha(opacity=50);  -moz-opacity:0.5;  -khtml-opacity: 0.5;  opacity: 0.5; }#mainContent { height:600px;filter:alpha(opacity=50);  -moz-opacity:0.5;  -khtml-opacity: 0.5;  opacity: 0.5; }#sidebar { float:left; width:200px; height:600px; background:#9ff;filter:alpha(opacity=50);  -moz-opacity:0.5;  -khtml-opacity: 0.5;  opacity: 0.5; }#sidebar2 { float:right; width:200px; height:600px; background:#9ff;filter:alpha(opacity=50);  -moz-opacity:0.5;  -khtml-opacity: 0.5;  opacity: 0.5; }#content {  height:600px; background:#cff;filter:alpha(opacity=50);  -moz-opacity:0.5;  -khtml-opacity: 0.5;  opacity: 0.5; }#footer { height:60px; background:#6cf;filter:alpha(opacity=50);  -moz-opacity:0.5;  -khtml-opacity: 0.5;  opacity: 0.5; }

这是页面代码：

<body>	<div id="container">		<div id="header">			<div id="up_left">				<h3>您好，欢迎光临论坛！</h3>				<script type="text/javascript">					var d = new Date()					document.write(d.getFullYear() + '年' + (d.getMonth() + 1)							+ '月' + d.getDate() + '日' + ' 星期'							+ '日一二三四五六'.charAt(new Date().getDay()));				</script>			</div>			<div id="up_right">				<form action="user/login.action" method="post">					姓名: <input type="text" name="userName" id="userName"> 密码: <input						type="password" name="password" id="password"> <input						type="submit" value="登录" /> <a href="user/register.action">点击注册....</a>				</form>			</div>		</div>		<div id="menu"><a href="diary/main.jsp">平凡的世界</a></div>		<div id="mainContent">			<div id="sidebar"><a href="diary/main.jsp">平凡的世界</a></div>			<div id="sidebar2"><a href="diary/main.jsp">平凡的世界</a></div>			<div id="content"><a href="diary/main.jsp">平凡的世界</a></div>		</div>		<div id="footer"><a href="diary/main.jsp">平凡的世界</a></div>	</div></body>

不用怀疑了，我给每个层都添加了这样的链接，其他的都可以，但就是id为"sidebar"和"sidebar2"的这两个层不行，
跳转不过去，这是为什么呢
