这篇文章给大家分享了两个鼠标悬浮出现说明遮罩层的效果，大家可以根据自己的需要选择某一种效果，两种效果文中都给出了实例代码，下面来一起看看吧。

先来一个简单的实现方法：

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>Document</title>
 <style type="text/css">
  .mask-wrapper {
      position: relative;
      overflow: hidden;
  }
  .mask-inner {
      position: absolute;
      left: 0;
      top: 100%;
      width: 100%;
      height: 100%;
      -moz-transition: top ease 200ms;
      -o-transition: top ease 200ms;
      -webkit-transition: top ease 200ms;
      transition: top ease 200ms;
  }
  .mask-wrapper:hover .mask-inner {
      top: 0;
  }
  #my-mask {
      width: 300px;
      height: 200px;
      background: red;
  }
  #my-mask .mask-inner {
      background: rgba(0,0,0,.5);
  }
 </style>
</head>
<body>
 <p id="my-mask" class="mask-wrapper">
    <p>Lorem ipsum</p>
    <p class="mask-inner">
        <p>foo bar</p>
    </p>
</p>
</body>
</html>

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">

      margin: 0;
      padding: 0;
  }
  body {
      font: 12px/1.5 arail;
  }
  ul {
      list-style: none;
  }
  .icon-lists {
      overflow: hidden;
      background: #f7f7f7;
      padding: 40px;
  }
  .icon-lists .box {
      float: left;
      margin-right: 10px;

  .box {
      position: relative;
      width: 46px;
      height: 46px;
      overflow: hidden;
      z-index: 1;

  .box i, .box .info {
      display: block;
      width: 46px;
