我试图给包装器一个背景，这样我就可以拥有一个无限的侧边栏。当我将相同的 CSS 规则应用到任何其他 HTML 元素时，背景会正确应用。由于某种原因，它无法在 .wrapper 上运行。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">
    <h1 id="banner">Packard Carburetors</h1>
</div><!--Header-->

<div id="navbar" class="green">
    <ul id="navigation">

尝试添加：

overflow: auto;

到你的包装类
