我试图创建一个简单的下拉菜单，但我不明白... 我现在看了一些教程，子菜单的位置很糟糕。我想要一个“正常”的下拉菜单，没什么特别的。问题可能是绝对位置，但在教程中他也使用了它。下拉菜单位于第二点 (Produkte)。这是我的页面:Page和代码:
*{
padding: 0px;
margin: 0px;

line-height: 20px;

background-image: url(images/hintergrund.png);

margin-left: auto;
margin-right: auto;
padding: 20px;
background-color: #fcb774;

使用 position: absolute 将元素从文档流中移除，并自然地成为相对于文档的元素。您需要使用 position: relative 将子菜单包含在其父项中。像这样将其添加到您的父 li 中:
nav ul li {
display: inline-block;
font-size: 16px;
position: relative; //add
}
