html - 无法将背景图像应用于 div
问题描述
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Portfolio</title>
<link rel="stylesheet" type="text/css" href="Project9.css">
<link rel="icon" type="image/png" href="https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-camera-512.png">
</head>
<body>
<div class="back">
</div>
</body>
</html>
*{
margin: 0;
padding: 0;
}
.back{
background-image: url(images/bg.jpg);
background-size: cover;
background-attachment: fixed;
background-repeat: no-repeat;
background-position: center;
}
背景图像不会显示在 (.back) div 中,但它确实适用于 body 标签。我已经检查了文件的名称和所有内容,但它显示为空白。
解决方案
你必须给 div awidth
和 a height
:
.back{
background-image: url("https://picsum.photos/200/300");
background-size: cover;
background-attachment: fixed;
background-repeat: no-repeat;
background-position: center;
height: 100px;
width: 100px;
}
<div class="back"></div>
