Bootstrap基本组件学习笔记之导航(10)
kikay 人气:0Bootstrap的导航很有特色,主要分为胶囊式导航、面包屑导航、头部导航共3大类,可以满足绝大部分需求。
0x01 胶囊式导航
胶囊式导航采用的是无序列表ul来实现:
<!DOCTYPE html> <html lang="zh-cn"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link href="../../css/bootstrap.min.css" rel="stylesheet"> <script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script> <script src="../../js/bootstrap.min.js"></script> <title>胶囊式导航</title> </head> <body> <div class="container"> <div class="page-header"> <h1>胶囊式导航</h1> </div> <div class="col-lg-3"> <h3>水平样式</h3> <ul class="nav nav-pills"> <li class="active"><a href="#">首页</a></li> <li><a href="#">新闻</a></li> <li><a href="#">关于</a></li> </ul> </div> <div class="col-lg-3"> <h3>垂直样式</h3> <ul class="nav nav-pills nav-stacked"> <li class="active"><a href="#">首页</a></li> <li><a href="#">新闻</a></li> <li><a href="#">关于</a></li> </ul> </div> </div> </body> </html>
效果如下:
0x02面包屑导航
面包屑导航采用的是有序列表ol来实现:
<!DOCTYPE html> <html lang="zh-cn"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link href="../../css/bootstrap.min.css" rel="stylesheet"> <script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script> <script src="../../js/bootstrap.min.js"></script> <title>面包屑导航</title> </head> <body> <div class="container"> <div class="page-header"> <h1>面包屑导航</h1> </div> <div class="breadcrumb"> <li class="active"><a href="#">学校</a></li> <li><a href="#">一年级</a></li> <li><a href="#">一班</a></li> </div> </div> </body> </html>

0x03 头部导航
头部导航在网站开发中比较常见,依赖于Bootstrap库的collapse插件。基本样式如下:
<!DOCTYPE html> <html lang="zh-cn"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link href="../../css/bootstrap.min.css" rel="stylesheet"> <style> /*body{*/ /*padding-top: 50px;*/ /*}*/ </style> <script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script> <script src="../../js/bootstrap.min.js"></script> <title>头部导航</title> </head> <body> <div class="container"> <nav class="navbar navbar-inverse"> <div class="navbar-header"> <button type="button" class="btn btn-default navbar-toggle" data-toggle="collapse" data-target="#navbar"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a href="#" class="navbar-brand">网站标题</a> </div> <div class="collapse navbar-collapse" id="navbar"> <ul class="nav navbar-nav"> <li class="active"><a href="#">首 页</a></li> <li><a href="#">新闻</a></li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown"> 下拉菜单 <span class="caret"></span> </a> <ul class="dropdown-menu"> <li><a href="#">菜单1</a></li> <li><a href="#">菜单2</a></li> <li><a href="#">菜单3</a></li> </ul> </li> </ul> <form class="nav navbar-form navbar-right"> <div class="form-group"> <input type="text" class="form-control" placeholder="用户名"> </div> <div class="form-group"> <input type="password" class="form-control" placeholder="密码"> </div> <div class="form-group"> <button type="submit" class="btn btn-primary form-control">提 交</button> </div> </form> </div> </nav> <div class="page-header"> <h1>头部导航</h1> </div> <div> <p>内容</p> </div> </div> </body> </html>

<span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span>
