我有以下代码在我的 CSS 样式表中显示横幅。
#banner {
background-image: url(../Images/banner.png);
background-repeat: no-repeat;
background-size: cover;
border: 5px solid #dedede;
height: 200px;
}
横幅未显示。相反，我在左上角得到了一个白色的小立方体。
完整的 CSS 样式表是:
body {
font-family: lucida grande,tahoma,verdana,arial,sans-serif;
background-color: #e9e9e9;
}
body p {
font-size: 0.8em;
line-height: 1.28;
}
#wrapper {
width: 1080px;
background-color: #fff;
margin: 0 auto;
padding: 10px;
border: 5px solid #dedede;
}
#banner {
background-image: url(../Images/banner.png);
background-repeat: no-repeat;
background-size: cover;
border: 5px solid #dedede;
height: 200px;
}
#content_area {
float: left;
width: 750px;
margin: 20px 0 20px 0;
padding: 10px;
}
#sidebar {
clear: right;
width: 250px;
height: 400px;
margin: 20px 10px;
padding: 10px;
border: 2px solid #E3E3E3;
}
footer {
clear: both;
width: auto;
height: 40px;
padding: 10px;
border: 3px solid #E3E3E3;
text-align: center;
color: #fff;
text-shadow: 0.1em 0.1em #333;
background-image: url(../Images/banner.jpg);
}
#navigation {
height: 60px;
border: 3px solid #E3E3E3;
margin-top: 20px;
text-shadow: 0.1em 0.1em #333;
background-image: url(../Images/footer.jpg);
}
#nav {
list-style: none;
}
#nav ul {
margin: 0;
padding: 0;
width: auto;
display: none;
}
#nav li {
font-size: 24px;
float: left;
position: relative;
width: 180px;
height: 50px;
}
#nav a:link, nav a:active, nav a:visited {
display: block;
color: #fff;
text-decoration: none;
}
#nav a:hover {
color: lightblue;
}
这是我的 HTML 代码:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title><?php echo $title; ?></title>
<link rel="stylesheet" type="text/css" href="Styles/Stylesheet.css"/>
</head>
<body>
<div id="wrapper">
<div id=banner">
</div>
<nav id="navigation">
<ul id="nav">
<li><a href="index.php">Home</a></li>
<li><a href="#">Books</a></li>
<li><a href="#">Publications</a></li>
<li><a href="#">About Us</a></li>
</ul>
</nav>
<div id="content_area">
<?php echo $content; ?>
</div>
<div id="sidebar"></div>
<footer>
<p>All rights reserved</p>
</footer>
</body>
</html>
最佳答案
id属性值好像双引号错误
<div id=banner">
