使用方法:
1、head引入css文件
<link type="text/css" href="css/style.css" rel="stylesheet" />
2、body引入HTML代码
<div class="out"> <div class="fade-in"> <div class="container"> <div class="one common"></div> <div class="two common"></div> <div class="three common"></div> <div class="four common"></div> <div class="five common"></div> <div class="six common"></div> <div class="seven common"></div> <div class="eight common"></div> </div> <div class="bar"> <div class="progress"></div> </div> </div> </div>
