css下拉菜单代码

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。

Q3: CSS技巧分享：如何用css制作横排二级下拉菜单

工具/材料

notepad++

浏览器

打开Notepad++，先输入个页面框架

！DOCTYPE html

html xmlns=""

hade

/hade

body

/body

框架好了，那么就该定义页面的title，关键词keyword，和描述description

meta charset="UTF-8" content="text/html" http-equiv="content-type"

title纯css二级导航下拉菜单/title

meta name="keyword" content="搜狗略懂"

meta name="description" content="描述"

这些内容只能在head/head中完成。

定义页面使用的css样式，也是需要在head里定义的。

style type="text/css"

* {

margin:0;

padding:0;

}

.jiao ul li a:hover{

color:#red;

}

ul, li {

list-style:none;

}

a {

text-decoration:none;

}

.jiao {

border:5px solid #pink;

border-right:none;

overflow:hidden;

float:left;

margin:200px 0 0 600px;

}

.jiao ul li ul li a {

border-right:solid;

border-top:2px dotted #666;

background:#black;

}

.jiaoulli { float:left;}

.jiao ul li a { width:150px; height:80px; text-align:center; line-height:100px; display:block; border-right:5px solid #red; background:#red; color:#red;}

.jiao ul li ul { position:absolute; display:none;}

.jiao ul li:hover ul{ display:block; }

.jiaoulliulli { float:none;}

!--navul只选择nav下一级里面的ul元素

nav ul选择nav内所包含的所有ul元素

navul比nav ul限定更严格，必须后面的元素只比前面的低一个级别。

这里根据你的需求来自己定义。

/style

添加一个DIV标签，在页面中划分出一个块来，用来显示。

div中所用的样式为刚才咱们声明的样式“jiao”这个盒子来描述

然后使用无序标签ul+样式li 来实现模块。

div class="jiao"
