css3轮播渐显效果 2016/11/29

css3因为其兼容性的问题，被我忽略很久，这次正好做到一个轮播渐显的效果，想了想，正好复习下css3的相关内容，废话不多说，直接上代码。

 <ul class="cb-slideshow">
        <li><span>Image 01</span></li>
        <li><span>Image 02</span></li>
        <li><span>Image 03</span></li>
        <li><span>Image 04</span></li>
        <li><span>Image 05</span></li>
        <li><span>Image 06</span></li>
    </ul>

html页面只是简单的放置几个img的容器。

重要的是这些
