html - 背景色中的导航

Question

我的导航栏有问题。我的导航栏不是我所在区 block 的背景色。我可以尝试 position:absolute 但不推荐这样做。

.transparent{
  width: 100%;
  height: 100px;
  margin-top: 10px;
  position: absolute;
  background-color: rgba(0,0,0,0.5);
  opacity: 1;
}

我卡住了。任何人都可以提供帮助或知道为什么代码不起作用吗？请帮忙。

也将 class="transparent" 添加到您的导航 HTML 元素中。或者你可以像其他人说的那样直接在 CSS 中设置你的 nav 元素的样式。

所以要么:

<nav class="transparent">
  <ul>
    <li><a class="active" href="index.php">Home</a></li>
    <li><a href="#">About us</a></li>
    <li><a href="#">Investement plan</a></li>
    <li><a href="#">News</a></li>
    <li><a href="#">Faqs</a></li>
    <li><a href="#">Rules</a></li>
    <li><a href="#">Contact us</a></li>
  </ul>
</nav>

或者:

nav {
  padding-top: 10px;
  padding-right: 120px;
  width: auto;
  background-color: rgba(0,0,0,0.5);
}
