这里写图片描述

任务
1，给每个列表定义不同的背景颜色
提示：使用结构伪类选择器:nth-of-type()

2，设置缩略图外形效果
提示：使用伪元素::after制作圆形效果

3、给每个缩略图设置不同的图片
提示：使用伪结构选择器:nth-of-type()，并且配合::after

4、给每个缩略图添加透明度蒙板效果
提示：使用伪类选择器::before给缩略图添加蒙板效果

5、鼠标悬浮在缩略图上时，修改缩略图上蒙板的透明度
提示：通过:hover和::before配合修改opacity的值为0

6、点击缩略图，切换背景图片
提示：通过目标选择器:target进行背景图片的切换

7、控制不是被点击图片的层级大小，让其不显示
提示：通过“否定选择器:not()”和“目标选择器:target”来控制不是被切换的背景图像不显示
