Question

我正在尝试给包装器一个背景，以便我可以拥有一个无限的侧边栏。当我将相同的CSS规则应用于任何其他HTML元素时，背景会正确应用。由于某种原因它只能在.wrapper上工作。这是HTML：

<html>
<head>
<title> Packard Carburetors </title>
<link rel="stylesheet" type="text/css" href="css/reset.css" />
<link rel="stylesheet" type="text/css" href="css/style.css" />
</head>
<body>

<div class="wrapper">

<div id="header">

Answer 1

尝试添加：

overflow: auto;

到你的包装类

背景图像不适用于包装器，但适用于其他HTML元素
