Navigation

Navigation is no stranger to a front-end person. It can be said that navigation is one of the important elements and components of a website, which can facilitate users to find various functional services provided by the website.

<nav class="nabber navbar-default" role="navigation"><!--导航条、默认样式、role定义内容是一个导航条-->
 <div class="container-fluid"><!--container居中固定宽度、c-f自适应大小的导航条-->
 <div class="navbar-header">
 
 <!--在响应式浏览器宽度小于一定值时，显示按钮-->
 <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
 <span class="sr-only">Toggle navigation</span>
 <span class="icon-bar"></span>
 <span class="icon-bar"></span>
 <span class="icon-bar"></span>
 </button>
 
 <!--logo图标-->
 <a class="navbar-brand" href="#">Brand</a>
 
 </div>
 
 <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"><!--包裹代码，在宽度大于一定值时，button和此代码是没有作用的-->
 
 <!--导航条导航项目-->
 <ul class="nav navbar-nav">
 <li class="active"><a href="#">a</a></li>
 <li><a href="#">a</a></li>
 </ul>
 </div>
 </div>
</nav>
 .navbar-inverse:改变导航条的背景颜色
 .container:居中显示
 固定导航条会遮盖页面内容，解决办法设置body的*padding-top*

Drop-down menu

Friends, please note that the drop-down menu component in the Bootstrap framework is an independent component.

<li class="dropdown">
 <a href="#" class="dropdown-toggle" data-toggle="dropdown">下拉菜单<span class="caret"></span></a>
 <ul class="dropdown-menu" role="menu">
 <li><a href="#">Action</a></li>
 <li><a href="#">Another action</a></li>
 <li><a href="#">Something else</a></li>
 <li class="divider"></li>
 <li><a href="#">linkkk/a></li>
 </ul>
</li>
