Bootstrap4 导航

由 平台活动 创建, 最后一次修改 2018-05-30

在Bootstrap4中,可以使用.nav类来创建导航,


简单的水平导航

如果你想创建一个简单的水平导航栏,可以在 <ul> 元素上添加 .nav类,在每个 <li> 选项上添加 .nav-item 类,在每个链接上添加 .nav-link 类。

实例:

<!DOCTYPE html>

  <h2>导航</h2>
  <p>简单的水平导航:</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>


导航对齐方式

导航默认左对齐,我们可以使用.justify-content-center 类设置导航居中显示, .justify-content-end 类设置导航右对齐。

实例:

<!DOCTYPE html>

    <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>
  <p class="text-right">右对齐导航:</p>

动态选项卡

如果你要设置选项卡是动态可切换的,可以在每个链接上添加 data-toggle="tab" 属性。 然后在每个选项对应的内容的上添加 .tab-pane 类。

如果你希望有淡入效果可以在 .tab-pane 后添加 .fade类:
