在我的 HTML 页面中，我想要以下内容:
- HTML 和正文占据屏幕的整个高度。不可滚动。
- 顶栏，固定，高度为 40 像素。
- 左侧栏，固定，宽度为 40 像素。
- 应该是可滚动的内容。
到目前为止，一切正常，但是，我似乎无法使内容部分在 y 方向上滚动，即使它溢出屏幕。我的代码如下所示:
<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css">
html, body {
height: 100%;
margin: 0;
padding: 0;
}
body {
overflow: hidden;
}
.top {
width: 100%;
height: 40px;
background: rgba(0, 0, 0, 0.5);
position: fixed;
top: 0;
left: 0;
}
.left {
width: 40px;
height: 100%;
background: rgba(0, 0, 0, 0.25);
position: fixed;
top: 40px;
left: 0;
}
.content {
max-width: 480px;
background: red;
margin-top: 40px;
margin-left: 40px;
overflow-y: auto;
}
</style>
</head>
<body>
<div class="top"></div>
<div class="left"></div>
<div class="content">

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

要使 overflow-y: auto 起作用，您需要指定 div 的 max-height。
