初学html和css，照葫芦画瓢实现无js的轮播，主要借鉴了以下两个博客：

主要就是利用了overflow的hidden和animation属性，宽度只要改slider的width就行了。animation时间的计算还有延时可以参考http://www.jianshu.com/p/28643f36011e，作者讲的很详细，不过他和我实现的方法和效果都不一样。以下是代码：
<html>
<head>
<title>slide</title>
</head>
<body>
<div class="slider-focus">
<div class="slider">
<ul class="slider-list">
<li class="slider-item slider-item1"></li>
<li class="slider-item slider-item2"></li>
<li class="slider-item slider-item3"></li>
</ul>
<ul class="focus-list">
<li class="focus-item focus-item1"></li>
<li class="focus-item focus-item2"></li>
<li class="focus-item focus-item3"></li>
</ul>
</div>
</div>
</body>
