<div id="banner">

<div id="menu">

    <li><a href="#page2">Page 2</a></a></li>
    <li><a href="#page3">Page 3</a></a></li>
    <li><a href="#page4">Page 4</a></a></li>

<div id="content">

Answer 1

1)

body {
  margin: 0;
}
#banner > h1 {
  margin: 0;
}

2)

#menu {
  margin: 0 auto;
}

3) 您必须将 <div id="content"></div> 添加到您的 HTML 并将 background-image 更改为 background 在您的 CSS.

Answer 2

将结束引号添加到 <div id="content"></div>

3) 这应该有效：

#content {
background: url(image.jpg) no-repeat center center;
background-size: cover;
width: 1050px;
height: 1000px;
margin: 0 auto;
}
