导航药丸在我的代码中不起作用（引导程序 4）

Question

I'm trying to add nav-pills to tag but it's not working, why? I really tried everything but nothing works!

<ul class="nav nav-pills flex-column">

  <li class="nav-item">
    <a class="nav-link" href="dashboard.php">Dashboard</a>
  </li>

  <li class="nav-item">
    <a class="nav-link" href="#">Add New Post</a>
  </li>

</ul>

Answer 1

Pills require the active class.

<ul class="nav nav-pills flex-column">
    <li class="nav-item">
        <a class="nav-link active" href="">Dashboard</a>
    </li>
    <li class="nav-item">
        <a class="nav-link" href="#">Add New Post</a>
    </li>
</ul>
