今天看了别人写的图片滑动，看起来很酷，读源码时，似乎有些困难，就模仿着写了一个，实现的效果与原网页相同，不过自己的js代码，逻辑简单，有待改进。
ps：前两天写了旋转木马，那个兼容性不好，今天写这个网页的时候，也是按照这个思路，在谷歌浏览器上运行很好，火狐很多功能不能实现，由于wrap——panel使用了绝对定位，就将translate平移改为了left。改动后，各个浏览器运行的效果不错。
具体代码如下
html代码（没写注释）
<div> <h1>Parallax Slider</h1> <div> <div> <div></div> <div></div> <div></div> </div> <div> <div> <img src="https://www.jb51.net/images/1.jpg"> </div> <div> <img src="https://www.jb51.net/images/2.jpg"> </div> <div> <img src="https://www.jb51.net/images/3.jpg"> </div> <div> <img src="https://www.jb51.net/images/4.jpg"> </div> <div> <img src="https://www.jb51.net/images/5.jpg"> </div> <div> <img src="https://www.jb51.net/images/6.jpg"> </div> </div> <div> <span></span> <span></span> </div> <div> <ul> <li><img src="https://www.jb51.net/images/thumbs/1.jpg"></li> <li><img src="https://www.jb51.net/images/thumbs/2.jpg"></li> <li><img src="https://www.jb51.net/images/thumbs/3.jpg"></li> <li><img src="https://www.jb51.net/images/thumbs/4.jpg"></li> <li><img src="https://www.jb51.net/images/thumbs/5.jpg"></li> <li><img src="https://www.jb51.net/images/thumbs/6.jpg"></li> </ul> </div> </div> </div>
css代码（自己对应着看）：
