Question

我的Bootstrap Navbar出现问题。它似乎在几个月前工作正常，但现在它只是奇怪的事情，不明白为什么。我最大的问题是，当我在小窗口尺寸上尝试扩展我的Navmenu时，它会在右侧而不是在实际的汉堡包下面。

这是我的导航代码：

<div class="menue">
      <nav class="navbar navbar-expand-lg navbar-light">
        <a class="navbar-brand" href="#">Kosmetik Asura</a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
              <span class="navbar-toggler-icon"></span>
            </button>
        <div class="collapse navbar-collapse" id="navbarNav">
          <ul class="navbar-nav mr-auto mt-2 mt-lg-0">
            <li class="nav-item">
              <a class="nav-link" href="#">Home</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="#ueber">Über</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="#angebote">Angebot</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="#news">News</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="#kontakt">Kontakt</a>
            </li>
          </ul>
        </div>
      </nav>
    </div>

有谁能告诉我需要改变什么？

提前致谢！

致评论：

我在扩展菜单的左边看到了一个黑色的条形图透明的。

从你的css中删除它：

 border-left: 2px solid black; 


box-shadow: inset 0px 0px 5px #000;
