Is it possible to use the nth-child with modulo? I know you can specify a formula, such as

nth-child(4n+2)

But I can't seem to find if there's a modulo operator. I've tried the following examples below, and none seem to work:

nth-child(n%7)
nth-child(n % 7)
nth-child(n mod 7)

If you want to use nth-child with modulo k, just specify:

nth-child(kn)

For example, if you want to specify style for 3, 6, 9, .. elements, just specify (k = 3), and use:

nth-child(3n)

You can also specify an offset:

nth-child(kn+offset)
