切換背景圖像綜合練習(xí)題
同學(xué)們，根據(jù)所學(xué)知識(shí)，使用CSS3知識(shí)，實(shí)現(xiàn)背景圖片的切換效果（不依賴(lài)js，點(diǎn)擊小圖切換大的背景圖）
任務(wù)
給每個(gè)列表定義不同的背景顏色
提示：使用結(jié)構(gòu)偽類(lèi)選擇器:nth-of-type()
設(shè)置縮略圖外形效果
提示：使用偽元素::after制作圓形效果
1、給每個(gè)縮略圖設(shè)置不同的圖片
提示：使用偽結(jié)構(gòu)選擇器:nth-of-type()，并且配合::after
2、給每個(gè)縮略圖添加透明度蒙板效果
提示：使用偽類(lèi)選擇器::before給縮略圖添加蒙板效果
3、鼠標(biāo)懸浮在縮略圖上時(shí)，修改縮略圖上蒙板的透明度
提示：通過(guò):hover和::before配合修改opacity的值為0
4、點(diǎn)擊縮略圖，切換背景圖片
提示：通過(guò)目標(biāo)選擇器:target進(jìn)行背景圖片的切換
5、控制不是被點(diǎn)擊圖片的層級(jí)大小，讓其不顯示
提示：通過(guò)“否定選擇器:not()”和“目標(biāo)選擇器:target”來(lái)控制不是被切換的背景圖像不顯示
