问题描述
我有一个 divs
列表,它与一个类连续出现 4 个,我想创建一个棋盘背景样式,意思是:
I have a list of divs
that appear 4 in a row with a class and I would like to create a checkerboard background style, meaning:
- 为奇数和偶数
div
应用不同的背景颜色 - 将每行的奇偶切换为奇偶
我试过了
.boxwrapper:nth-child(2n-1), .boxwrapper:nth-child(2n) {
background:#ff0000;
}
.boxwrapper:nth-child(4n-2), .boxwrapper:nth-child(4n-3) {
background:#0000ff;
}
它适用于奇偶 div,但不能让它每 4 个项目切换一次.我正在为 4n-1、4n+1 的事情头疼,如果我能做到这一点,瞧!
and it works fine for odd-even divs but cant get it to switch every 4 items. I'm headaching over the 4n-1, 4n+1 stuff, if I could get that right voila!
结果应该是这样的:
