CSS is even odd for every other odd div in the class

Question

I have divs in a horizontal line, all in one class, for example:

1 2 3 4 5 6 7 8 9 10

I want to use css for every other odd line, so 1,5,9, etc.

I tried

.myClass:nth-child(n+4) and .myClass:nth-child(odd),.myClass:nth-child(odd){ 

but can not understand: (

Answer 1

:nth-child(4n) gives us 0, 4, 8, etc.

Since you want 1, 5, 9, you should try :nth-child(4n + 1)

Answer 2

What you want to do is apply CSS to every fourth line, so you want:

 .myClass:nth-child(4n+1)
