I'm having my hexagons float:left in a body of a certain width. I can effectively accomplish the results in the link above if I can select the first element in every other row. What would be the nth-child formula for that?

It would be the 5th element, then every 7th element after that?

Answer 1

公式是:nth-child(7n+5)。代表“7n每 7 个元素”，+5代表“从第 5 个元素开始”。
