我试图用替代颜色创建一个2列网格(第一个单元格为红色,第二个为黄色,第三个为黄色,第四个为红色等等)
使用3 cols网格我没有问题,但有了这种布局,我会发疯= _ =
有人可以帮助我吗?

您可以使用此选择器:nth-child()
:
/*Every 2 rows from 0 (even) - Every 2 cells from 0 (even)*/
.row:nth-child(2n+0) div:nth-child(2n+0) {
background: #ff0000;
}
/*Every 2 rows from 0 (even) - Every 2 cells from 1 (odd)*/
.row:nth-child(2n+0) div:nth-child(2n+1) {
background: #ffff00;
}
/*Every 2 rows from 1 (odd) - Every 2 cells from 0 (even)*/
.row:nth-child(2n+1) div:nth-child(2n+0) {
background: #ffff00;
}
/*Every 2 rows from 1 (odd) - Every 2 cells from 1 (odd)*/
.row:nth-child(2n+1) div:nth-child(2n+1) {
background: #ff0000;
}
可以像这样简化:
.row:nth-child(even) div:nth-child(even) {
background: #ff0000;
}
.row:nth-child(even) div:nth-child(odd) {
background: #ffff00;
}
.row:nth-child(odd) div:nth-child(even) {
background: #ffff00;
}
.row:nth-child(odd) div:nth-child(odd) {
background: #ff0000;
}
