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 id="您好-欢迎光临论坛">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
回复讨论(解决方案)
你是给文字加了超链接，并不是div。
写成这样：
你是给文字加了超链接，并不是div。
写成这样：
我知道原因了，因为它是三个平行的层，"sidebar"和"sidebar2"分别是向左和向右的层，中间的"content"覆盖住了它们
然后我上网查了一下，说是用position:absoulte;z-index:5555;
为什么我加了没用啊
这个要怎样才能中间的"content"层浮到最下面去
margin-left: 100px;
你给content层定一个宽度800px;然后float:left.
好啦，我在content里面加了margin:0 200px;就刚好啦，谢谢啦
