  <!-- Navigation -->
  <nav class="navbar navbar-expand-lg  fixed-top text-uppercase bg-inverse" id="mainNav">
    <div class="container">
      <a class="navbar-brand js-scroll-trigger" href="#page-top"><img style="height: 80px;" src="img/logobanner.png" alt=""></a>
      <button class="navbar-toggler navbar-toggler-right text-uppercase bg-primary text-white rounded" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
        Menu
        <i class="fas fa-bars"></i>
      </button>
      <div class="collapse navbar-collapse" id="navbarResponsive">
        <ul class="navbar-nav ml-auto">
          <li class="nav-item mx-0 mx-lg-1">
            <a class="nav-link py-2 px-0 px-lg-3 rounded js-scroll-trigger" href="#page-top">Home</a>
          </li>
          <li class="nav-item mx-0 mx-lg-1">
            <a class="nav-link py-2 px-0 px-lg-3 rounded js-scroll-trigger" href="#about">2</a>
          </li>
          <li class="nav-item mx-0 mx-lg-1">
            <a class="nav-link py-2 px-0 px-lg-3 rounded js-scroll-trigger" href="#portfolio">Foto's</a>
          </li>
          <li class="nav-item mx-0 mx-lg-1">
            <a class="nav-link py-2 px-0 px-lg-3 rounded js-scroll-trigger" href="#portfolio2">Agenda</a>
          </li>
          <li class="nav-item mx-0 mx-lg-1">
            <a class="nav-link py-2 px-0 px-lg-3 rounded js-scroll-trigger" href="#contact">Boeken</a>
          </li>
        </ul>
      </div>
    </div>
  </nav>

在电话上查看时，您可以向右滚动，只有空白和汉堡菜单。也许我忘了加一堂课吗？

Answer 1

您是否在引用bootstrap js，jquery等？如果没有，请将它们添加到正文的末尾。它是在我这端完成的，还是有效的。

它没有任何样式，但是您应该明白了：https://jsfiddle.net/enstL6j7/1/

我认为CDN有问题。尽量不要使用jquery slim版本，因为有时它可能会引起问题。
