css下拉菜单代码,第1张

我给楼主看了一下```你要的效果没说清楚`如果想显示出下拉列表直接删掉 #menu li dd{display:none

}

就可以了。如果想鼠标移动后,出现下拉列表,我没看到楼主定义这个类型,所以给楼主一个我以前写的,仅供参考。

css制作横排二级下拉菜单,代码如下:

<body>

<ul id="FM">

<li><a href="#">一级栏目</a>

<ul>

<li><a href="#">二级菜单</a></li>

<li><a href="#">二级菜单</a></li>

<li><a href="#">二级菜单</a></li>

</ul>

</li>

<li><a href="#">一级栏目</a>

<ul>

<li><a href="#">二级菜单</a></li>

<li><a href="#">二级菜单</a></li>

<li><a href="#">二级菜单</a></li>

</ul>

</li>

<li><a href="#">一级栏目</a>

<ul>

<li><a href="#">二级菜单</a></li>

<li><a href="#">二级菜单</a></li>

<li><a href="#">二级菜单</a></li>

</ul>

</li>

</ul>

</body>

CSS样式设置代码,如下;

<style type="text/css">

ul#FM li {

float:left

width:160px

list-style:none

}

ul#FM li ul {

display:none

margin:0

padding:0

}

ul#FM li:hover ul{

display:block

}

ul#FM li a{

display:block

border:1px solid red

text-decoration:none

color:#000

}

ul#FM li li a {

display:block

font-size:12px

border:1px solid green

padding:3px

text-decoration:none

width:152px

color:#CC3399

}

ul#FM>li li a {

width:auto

}

</style>

所做出来的效果,鼠标放上去时,如图;

设置子菜单项的样式分为3步 1、首先对每个子菜单项,也就是dd元素进行常规设置,包括内外边距清零,设置文字颜色等。

/* 设置菜单项的dd */

#menu li dd {margin:0padding:0color: #fff

} 2、为了使最后一个dd的下端有一条分割线,我们设置它为1px的红色下边框,这就使之与上边框的红色分割线想对应了,也告诉浏览者这是一块可以点击的区域。

#menu li dd.last {

border-bottom:1px solid #b00

} 上面的代码也新增了一个last的类,因此我们必须在对应的HTML代码中最后一个dd指定class="last"。

CSS高级教程 3、设置子菜单的链接的样式

#menu li dd a, #menu li dd a:visited {

display:block

color:#FFF

text-decoration:none

padding:5px 20px

background: #0000FF}此时,我们在浏览器就可以看到下拉菜单的样式已经可以显示了。 二、设置鼠标经过时的响应

最后一条规则,让鼠标滑过有下拉项的时候,显示下拉菜单。当然我们实际设置的是:如果某一个下拉菜单的父级元素(一级菜单项)被鼠标滑过,那么就让该下拉菜单可以被看见:

#menu li dd { visibility: visible}

background: #0000FF}最后我们就可以运行整个文件实现效果了,建站教程网建议大家一起跟着步骤一步一步的做哦。
