实际效果：
思路：
1、先根据页面编写骨架屏页面及样式
2、在最外层元素标签上添加“透明度动画”即可
3、根据实际业务逻辑控制显示/隐藏
代码如下：
HTML部分
<!DOCTYPE html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no">
<title>Document</title>
<link rel="stylesheet" href="./uskeleton.css">
</head>
<body>
<div class="u-skeleton-container u-skeleton--animate">
<ul class="u-skeleton-box">
<!-- 可根据实际需要增添 li -->
<li>
<div class="u-skeleton-left"></div>
<div class="u-skeleton-right">
<p style=" 80%;"></p>
<p style=" 60%;"></p>
<p style=" 40%;"></p>
<p style=" 40%;"></p>
<p style=" 20%;"></p>
<button class="u-skeleton-btn"></button>
</div>
</li>
</ul>
</div>
</body>
</html>
