css3基礎-切換背景影象綜合練習題

這裡寫圖片描述

任務
1,給每個列表定義不同的背景顏色
提示:使用結構偽類選擇器:nth-of-type()

2,設定縮圖外形效果
提示:使用偽元素::after製作圓形效果

3、給每個縮圖設定不同的圖片
提示:使用偽結構選擇器:nth-of-type(),並且配合::after

4、給每個縮圖新增透明度蒙板效果
提示:使用偽類選擇器::before給縮圖新增蒙板效果

5、滑鼠懸浮在縮圖上時,修改縮圖上蒙板的透明度
提示:通過:hover和::before配合修改opacity的值為0

6、點選縮圖,切換背景圖片
提示:通過目標選擇器:target進行背景圖片的切換

7、控制不是被點選圖片的層級大小,讓其不顯示
提示:通過“否定選擇器:not()”和“目標選擇器:target”來控制不是被切換的背景影象不顯示
