我是引导世界的新手。有没有办法使用 Bootstrap 放置水印?如果有,请帮助我提供示例代码:

<!DOCTYPE html>
<html lang="en">
<head>
<title>Watermark sample code</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<br>
<div class="panel panel-primary">
<div class="panel-heading">
Watermark sample code
</div>
<div class="panel-body">
<div class="row">
<div class="col-lg-12">
First Line
</div>
<div class="col-lg-12">
Second Line
</div>
<div class="col-lg-12">
Third Line
</div>
</div>
</div>
</div>
</div>
</body>
</html>

最佳答案

您可以在 Body Tag 中放置水印或在 div 中使用此代码。
根据您的要求将不透明度从 0 更改为 1

  body {  
display: block;
position: relative;
height:100%;
width:100%;
}

body::after {
content: "";
background:url(https://www.google.co.in/images/srpr/logo11w.png) no-repeat;
opacity: 0.2;
top: 0;
left: 0;
bottom: 0;
right: 0;
position: absolute;
z-index: 1;
height:100%;
width:100%;
}
