count increments?

Hello!

For this website https://www.outofthegreencloset.com/

I’m outputting a footer with a list of all previous posts.

I display them in rows of three. Would be nice if the loop outputted only multiples of three.

I tried count=”3n” but that just translated into “3” haha.

Is there a way to do this?

Thanks

Janco
