天气好冷，都不想写代码。就先写个没有焦点的轮播图，过两天在补全。
用的是CSS3的属性 过渡transition 和 转换 transfrom:translateX()
只做了轮播和 鼠标进入停止轮播，离开继续轮播这几项。

var banner = document.querySelector('.banner');
//获取宽度
var bannerWidth = banner.offsetWidth;
//获取Ul
var moveUl = document.querySelector('ul');
//获取li
var lis = document.querySelectorAll('li');
//循环遍历li 为li绑定index
for (var i = 0; i < lis.length; i++) {
