Question

我尝试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，子菜单的位置是垃圾。我想要一个“正常”的下拉菜单没什么特别的。问题可能是位置绝对，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;
    font-family: Raleway;
    line-height: 20px;
	color: #003399;
}

body{
    background-image: url(images/hintergrund.png);
}

section{
    margin-top: 50px;
    width: 1100px;
    background: white;
    border: 2px solid black;
	box-shadow: 8px 8px 10px 0px rgba(0,0,0,0.75);
    
    margin-left: auto;
    margin-right: auto;
    padding: 20px;
    background-color: #fcb774;
}

article{
    width: 100%;
}

article:after{
   content: '';
   display: block;
   clear: both;
}

.bild{
    height: 200px;
    width: 200px;
    float: left;
    border: 2px solid black;
	box-shadow: 8px 8px 10px 0px rgba(0,0,0,0.75);
    overflow: hidden;
}

.bild:hover{
    cursor:pointer;
}

.text{
    float: right;
    width: 860px;
    word-wrap: break-word;
    height: 200px;
    border: 2px solid black;
	box-shadow: 8px 8px 10px 0px rgba(0,0,0,0.75);
    background-color: white;
}

hr{
    margin-top: 50px;
    margin-bottom: 50px;
    border: 1px solid black;
}

nav{
    width: 100%;
}

nav ul{
    background-color: #fcb774;
    margin: 0px;
    padding: 0px;
    text-align: center;
	font-size: 0;
	border-bottom: 2px solid black;
	box-shadow: 8px 8px 10px 0px rgba(0,0,0,0.75);
}

nav ul li{
    display: inline-block;
	font-size: 16px;
}

nav ul li a{
    display: block;
    padding: 10px 20px 10px 20px;
    transition: all 0.5s;
    text-decoration: none;
}

nav ul li a:hover{
    background-color: white;
    text-decoration: underline;
}

.dropdown{
    display:none;
    position: absolute;
    top: 30px;
    left: 0;
    width: 100px;
}

nav ul li:hover .dropdown{
    display: block;
}

Answer 1

使用position: absolute从文档流中删除元素，并且本质上变为相对于文档。您需要使用position: relative在其父级中包含子菜单。将其添加到您的父li，如下所示：

nav ul li {
   display: inline-block;
   font-size: 16px;
   position: relative; //add
}
