Bootstrap 导航

Bootstrap 标签

Bootstrap 菜单

大多数网页中都使用菜单。这些在无序列表中定义。您必须将 .list-inline类添加到才能创建水平菜单。

请参见以下示例:

<!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>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>
<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>
</body>
</html>

Bootstrap 标签

您可以使用创建基本的导航标签。您还可以使用

标记当前页面。

以下示例指定了如何创建简单的导航选项卡。

请参见以下示例:

<!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>
  <br>
  
</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>
</body>
</html>

带有下拉菜单的Bootstrap 选项卡

您还可以在下拉菜单中使用选项卡。

请参见以下示例:

<!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 With Dropdown Menu</h3>
  <ul class="nav nav-tabs">
    <li class="active"><a href="#">Home</a></li>
    <li class="dropdown">
      <a class="dropdown-toggle" data-toggle="dropdown" href="#">Menu 1 <span class="caret"></span></a>
      <ul class="dropdown-menu">
        <li><a href="#">Submenu 1-1</a></li>
        <li><a href="#">Submenu 1-2</a></li>
        <li><a href="#">Submenu 1-3</a></li>                        
      </ul>
    </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>
</body>
</html>

Bootstrap 可切换/动态选项卡

向每个链接添加 data-toggle ="tab" 属性。然后为每个标签添加一个具有唯一ID的 .tab窗格类，并将其包装在具有 class .tab-content 的<div>元素中，以使标签可切换。

如果您希望标签在单击时淡入和淡出，请在 .tab窗格中添加 .fade类。

查看此示例:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Case</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">

Bootstrap 4标签/导航

导航菜单

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类添加到元素中，然后为每个
添加.nav-item并将.nav-link类添加到其链接中。

示例:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <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">
      <a class="nav-link" href="#">Link</a>
    </li>
    <li class="nav-item">
      <a class="nav-link disabled" href="#">Disabled</a>
    </li>
  </ul>
</div>
</body>
</html>

对齐的导航

默认情况下，导航栏是左对齐的。

对于居中对齐: 添加.justify-content-center类以使导航中心居中对齐。

用于右对齐: 添加.justify-content-end类以将导航右对齐。

示例:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">

      <a class="nav-link disabled" href="#">Disabled</a>
    </li>
  </ul>
</div>

合理的标签/导航

对于合理的标签/导航，请添加.nav对齐的类(等宽):

示例:

<!DOCTYPE html>
<html lang="en">

<div class="container">
  <h2>Justified Tabs/Pills Example</h2>
  <p>To justify tabs/pills (equal width), use the .nav-justified class:</p>
  <ul class="nav nav-pills nav-justified">
    <li class="nav-item">
      <a class="nav-link active" href="#">Active</a>
    </li>
    <li class="nav-item">
