html - 两个链接不显示

Question

我在页眉组件中键入了 2 个链接，但这些链接没有显示。这很奇怪，因为一切似乎都很好。这 2 个链接在 ul 列表中。

<nav class="navbar navbar-expand-lg navbar-dark" style="background-color: #563F7A">
    <a class="navbar-brand" href="#">Ürün Listesi</a>
    <div class="collapse navbar-collapse" id="navbarSupportedContent">
      <ul class="navbar-nav mr-auto">
        <li class="nav-item">
          <a class="nav-link" href="#">Ürün İşlemleri</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Ürün Çıkışı</a>
        </li>
      </ul>
    </div>
  </nav

Answer 1

您的问题出在您包含的 div 上:

<div class="collapse navbar-collapse" id="navbarSupportedContent">

collapse 类将隐藏您的 div，因为它添加了样式 display: none(如果 .show未添加)，您需要删除它才能看到您的链接:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

<nav class="navbar navbar-expand-lg navbar-dark" style="background-color: #563F7A">
  <a class="navbar-brand" href="#">Ürün Listesi</a>
  <div class="navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item">
        <a class="nav-link" href="#">Ürün İşlemleri</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Ürün Çıkışı</a>
      </li>
    </ul>
  </div>
</nav>
