导航栏未正确堆叠

Question

在超小尺寸屏幕中，我希望将 navbar-brand 和 navbar-nav 垂直堆叠。<nav class="navbar navbar-dark navbar-expand-sm bg-primary fixed-top">    <div class="container">        <a class="navbar-brand" href="#">Ristorante Con Fusion</a>        <ul class="navbar-nav mr-auto">            <li class="nav-item active"><a class="nav-link" href="#">Home</a></li>            <li class="nav-item"><a class="nav-link" href="./aboutus.html">About</a></li>            <li class="nav-item"><a class="nav-link" href="#">Menu</a></li>            <li class="nav-item"><a class="nav-link" href="#">Contact</a></li>        </ul>    </div></nav>但由于某种原因，它看起来像这样如何在超小尺寸屏幕中拥有 navbar-brand 下的 navbar-nav？

Answer 1

您是否希望导航项也垂直堆叠？我想你正在寻找这个...

<nav class="navbar navbar-dark navbar-expand bg-primary fixed-top">

    <div class="container flex-column flex-sm-row">

        <a class="navbar-brand" href="#">Ristorante Con Fusion</a>

        <ul class="navbar-nav mr-sm-auto mr-0">

            <li class="nav-item active"><a class="nav-link" href="#">Home</a></li>

            <li class="nav-item"><a class="nav-link" href="./aboutus.html">About</a></li>

            <li class="nav-item"><a class="nav-link" href="#">Menu</a></li>

            <li class="nav-item"><a class="nav-link" href="#">Contact</a></li>

        </ul>

    </div>

</nav>

Answer 2

使用.collapse类和按钮切换器。

更新

只需在标签中添加flex-column flex-lg-row类即可nav。

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css">

<nav class="navbar navbar-expand-lg navbar-light bg-light flex-column flex-lg-row">

  <a class="navbar-brand" href="#">Navbar</a>

  <ul class="navbar-nav mr-auto">

      <li class="nav-item active"><a class="nav-link" href="#">Home</a></li>

      <li class="nav-item"><a class="nav-link" href="./aboutus.html">About</a></li>

      <li class="nav-item"><a class="nav-link" href="#">Menu</a></li>

      <li class="nav-item"><a class="nav-link" href="#">Contact</a></li>

    </ul>

</nav>
