什么阻止导航栏出现以及如何修复它？

问题描述 投票：0回答：3

在我的网站上完成，导航栏不起作用，虽然我一直在尝试使用我知道的每种技术来找出原因。我使用过z-index，但它也没用。

您的HTML代码结构不合理，<a>在<ul>之前关闭，尝试更新它：

  <li>
    <a>Inriktningar</a>
    <ul>
      <li><a href="teater.html">Teater</a></li>
      <li><a href="musik.html">Musik</a></li>
      <li><a href="dans.html">Dans</a></li>
      <li><a href="ljudteknik.html">Ljudteknik</a></li>
    </ul>
  </li>

要显示导航，请使用z-index:10;：

header ul li{
    float: right;
    list-style: none;
    position: relative;
    z-index:10;
}

试试这个小提琴：https://jsfiddle.net/6rg3tqyu/

你差不多完成了，只需从css行号中的ul中删除或更新z-index属性。 61。

header ul li:hover ul{
display: inline-block;
z-index: 1;

}

header a{
    color: #ffffff;
    text-decoration: none;
    text-transform: uppercase;
    font-size: 16px;
}

这会覆盖你的a链接到白色的颜色，所以你无法看到它们。
