本文概述
引导菜单
在大多数网页中都使用菜单。这些在无序列表<ul>中定义。你必须将.list-inline类添加到<ul>才能创建水平菜单。
请参阅以下示例:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Case</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<h3>Inline List</h3>
<ul class="list-inline">
<li><a href="#">Home</a></li>
<li><a href="#">Menu 1</a></li>
<li><a href="#">Menu 2</a></li>
<li><a href="#">Menu 3</a></li>
</ul>
</div>

引导选项卡
你可以使用<ul class =“ nav nav-tabs”>创建基本的导航标签。你也可以使用<li class =“ active”>标记当前页面。
以下示例指定如何创建一个简单的导航选项卡。
请参阅以下示例:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Case</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
</head>
<body>
<div class="container">
<h3>Tabs</h3>
<ul class="nav nav-tabs">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Menu 1</a></li>
<li><a href="#">Menu 2</a></li>
<li><a href="#">Menu 3</a></li>
</ul>

</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

<h3>Tabs With Dropdown Menu</h3>
<ul class="nav nav-tabs">
<li class="active"><a href="#">Home</a></li>

<ul class="dropdown-menu">
<li><a href="#">Submenu 1-1</a></li>

Bootstrap可切换/动态选项卡
将data-toggle =“ tab”属性添加到每个链接。然后为每个选项卡添加一个具有唯一ID的.tab-pane类,并将它们包装在具有.tab-content类的<div>元素内,以使标签可切换。
如果希望在单击时淡入淡出选项卡,请将.fade类添加到.tab-pane。
请参阅以下示例:
<!DOCTYPE html>

Bootstrap 4 tab/pill
没有菜单
导航菜单是网站中使用的导航菜单。如果要在网站中创建简单的水平菜单,请将.nav类添加到<ul>元素,然后为每个<li>添加.nav-item并将.nav-link类添加到其链接。
例:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.6/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<h2>Nav Example</h2>
<p>Basic horizontal menu:</p>
<ul class="nav">
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">

</ul>
</div>
</body>
</html>
对齐导航
默认情况下,导航左对齐。
对于居中对齐:添加.justify-content-center类以使导航居中对齐。
对于右对齐:添加.justify-content-end类以使导航右对齐。
