html - 下拉菜单未对齐

Question

我目前正在为一家直升机滑雪公司制作网站，但我在使用下拉菜单时遇到了问题。由于某种原因，它没有正确对齐。我在这个网站上看过类似的帖子来寻找答案，似乎将父元素的位置设置为 relative 并将子元素的位置设置为 absolute 是最常见的答案；但是，这对我不起作用。可能是因为我将它应用于错误的父/子元素；但我尝试了很多不同的选择，但似乎没有任何效果。下面是我的代码(我遇到了 jsfiddle 的问题，我对其他元素感到非常沮丧，无法解决另一个问题)。我也知道我的 css 代码很乱，需要稍微清理一下。感谢您的帮助

HTML:

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

                        <ul class="drop-down">
                            <li class="drop-down-items"><a href="#">Alaska Trip</a></li>

Answer 1

这是因为你的css样式中的padding-inline-start，你可以删除样式或向下拉菜单添加内联样式，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>
