Question

我目前正在为一家直升机滑雪公司制作网站，但下拉菜单出现问题。由于某种原因，它无法正确对齐。我已经在该网站上的类似帖子中找到了答案，似乎最常见的答案是将父元素的位置设置为相对，并将子元素的位置设置为绝对。但是，这对我不起作用。可能是因为我将其应用于错误的父/子元素；但我尝试了许多不同的选择，但似乎没有任何效果。下面是我的代码（我遇到了jsfiddle问题，对其他项目感到沮丧，无法解决另一个问题）。我也知道我的CSS代码是一团糟，需要进行一些清理。谢谢您的帮助

HTML：

<header>
    <a name="top"></a>

Answer 1

这是由于CSS样式中的padding-inline-start导致，您可以删除样式或将内联样式添加到下拉菜单中，如下所示

<ul class="drop-down" style="padding-inline-start: 0;">
  <li class="drop-down-items"><a href="#">Alaska Trip</a></li>
  <li class="drop-down-items"><a href="#">Chile Trip</a></li>
  <li class="drop-down-items"><a href="#">Argentina Trip</a></li>
</ul>

下拉菜单未对齐
