1、轮播图部分，右边鼠标移入，左边对应展示轮播图
可以在swiper 官网
选择vue中使用swiper
npm i swiper
左右两边的联动：左边的轮播图和右边的小的列表他们的列表组成结构是一样的，都是一样的数组，这样才能够在右边鼠标移入的时候获取到下标与左边的下标相对应 找到对应的元素。
2.右侧鼠标移入高亮
通过视频可以看出，鼠标高亮部分 紫色背景没有被其他的图片所盖住，而是展示在了上面的位置，因此，给每一个列表都单独添加一个div盒子来写紫色高亮部分，使用绝对定位来决定盒子的位置，在通过z-index 来控制盒子里面的内容层级关系，通过index属性来进行判断是否紫色盒子是否展示的问题。
