Bootstrap CSS组件之导航(nav)

春季来好快,悄无声息不知不觉中,草儿绿了,枝条发芽了,遍地野花油菜花开灿烂多姿,一切沐浴着春晨曙光,春风中摇弋轻摆,仿佛少女轻歌曼舞,楚楚动人。

本文实例为大家分享了Bootstrap导航的具体代码,供大家参考,具体内容如下

//源码
.nav {
 padding-left: 0;
 margin-bottom: 0;
 list-style: none;
}
.nav > li {
 position: relative;
 display: block;
}
.nav > li > a {
 position: relative;
 display: block;
 padding: 10px 15px;
}
.nav > li > a:hover,
.nav > li > a:focus {
 text-decoration: none;
 background-color: #eee;
}
.nav > li.disabled > a {
 color: #777;
}
.nav > li.disabled > a:hover,
.nav > li.disabled > a:focus {
 color: #777;
 text-decoration: none;
 cursor: not-allowed;
 background-color: transparent;
}

和默认的.btn样式不同,默认的.nav样式不提供默认的导航,必须通过附加另外一个样式才行,比如.nav-tabs样式表示选项卡导航。
nav nav-tabs nav-pills nav-stacked nav-justified navbar

1.选项卡导航(nav nav-tabs)
2.胶囊式选项卡导航(nav nav-pills)
3.堆叠式导航(nav nav-pills nav-stacked)
4.自适应导航(nav nav-tabs/nav-pills nav-justified)
5.二级导航(nav nav-tabs dropdown dropdown-menu)

例子见导航.html

<!DOCTYPE html>
<html lang="en">
 <head>
 <meta charset="utf-8">
 <meta http-equiv="X-UA-Compatible" content="IE=edge">
 <!-- Bootstrap从3.0版本开始全面支持移动平台,贯彻移动先行宗旨 -->
 <meta name="viewport" content="width=device-width, initial-scale=1">

 <!-- Bootstrap -->
 <link rel="nofollow noopener noreferrer" href="bootstrap-3.3.7-dist/css/bootstrap.min.css" rel="stylesheet">

 </head>
 <body>
 <!--选项卡导航nav nav-tabs:
  菜单当前高亮菜单项.active
  菜单项是禁用状态.disabled -->
 <ul class="nav nav-tabs">
  <li class="active"><a rel="nofollow noopener noreferrer" href="#">主页</a></li>
  <li><a rel="nofollow noopener noreferrer" href="#">个人信息</a></li>
  <li class="disabled"><a rel="nofollow noopener noreferrer" href="#">作品</a></li>
 </ul>

 <!-- 胶囊式选项卡导航nav nav-pills:
  .active的菜单会进行背景色高亮显示-->
 <ul class="nav nav-pills">
  <li class="active"><a rel="nofollow noopener noreferrer" href="#">主页</a></li>
  <li><a rel="nofollow noopener noreferrer" href="#">个人信息</a></li>
  <li class="disabled"><a rel="nofollow noopener noreferrer" href="#">作品</a></li>
 </ul>

 <!-- 堆叠式导航nav nav-pills nav-stacked:
  堆叠式导航的原理是去除nav-pills样式得浮动显示(默认不设置浮动,让其垂直摆放)-->
 <ul class="nav nav-pills nav-stacked">
  <li class="active"><a rel="nofollow noopener noreferrer" href="#">主页</a></li>
  <li><a rel="nofollow noopener noreferrer" href="#">个人信息</a></li>
  <li class="nav-divider"></li>
  <li class="disabled"><a rel="nofollow noopener noreferrer" href="#">作品</a></li>
 </ul>

 <!-- 自适应导航nav nav-pills/nav-tabs nav-justified:
  可以将li元素充满整个父元素,在宽度为100%的基础上,设置每个元素的display风格是table-cell-->
 <ul class="nav nav-pills nav-justified">
  <li class="active"><a rel="nofollow noopener noreferrer" href="#">主页</a></li>
  <li><a rel="nofollow noopener noreferrer" href="#">个人信息</a></li>
  <li class="disabled"><a rel="nofollow noopener noreferrer" href="#">作品</a></li>
 </ul>

 <!-- 二级导航nav nav-tabs:
  普通导航里的li元素作为父元素容器,内部包含dropdown下拉菜单的-->
 <ul class="nav nav-tabs">
  <li class="active"><a rel="nofollow noopener noreferrer" href="#">主页</a></li>
  <li><a rel="nofollow noopener noreferrer" href="#">个人信息</a></li>
  <li class="disabled"><a rel="nofollow noopener noreferrer" href="#">作品</a></li>
  <li class="dropdown">
  <a rel="nofollow noopener noreferrer" href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <span class="caret"></span></a>
  <ul class="dropdown-menu">
   <li><a rel="nofollow noopener noreferrer" href="#">二级菜单</a></li>
   <li><a rel="nofollow noopener noreferrer" href="#">二级菜单</a></li>
   <li><a rel="nofollow noopener noreferrer" href="#">二级菜单</a></li>
  </ul>
  </li>
 </ul>


 <!-- bootstrap是基于jQuery-->
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
 <script src="bootstrap-3.3.7-dist/js/bootstrap.min.js"></script>
 </body>
