我的网站上有一个页面，当我将鼠标悬停在其中一张图片上时，会出现一个带有图片标题的叠加层。以下是其中一张图片的代码：
<div id="content">
<div class="mosaic-block fade">
<a target ="_blank" href = "files/file1.pdf" class="mosaic-overlay">
<div class="details">
<h4>Form #1</h4>
<p>Permission Slip</p>
</div>
</a>
<div class="mosaic-backdrop"><img src="img/thumb1.jpg"/></div>
</div>
在我的标题中链接了这些样式表/脚本，图像和叠加层工作
<link rel="stylesheet" href="css/mosaic.css" type="text/css" media="screen" />
<link rel="stylesheet" href="../events/eventInfoStyle.css" type="text/css" media="screen" />
<link rel="stylesheet" type="text/css" href="../events/headbar.css">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
<script type="text/javascript" src="../events/header.js"></script>
<script type="text/javascript" src="js/mosaic.1.0.1.js"></script>
但是当我添加引导程序时，图像不再出现。以下是我正在添加的引导程序。
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<!-- Latest compiled JavaScript -->
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
什么导致图像在添加Bootstrap时不出现？ 这是我的其余CSS：

您的.fade类也是一个引导类。将其重命名为my-fade并查看是否可以。
