Susy not removing last padding of item

Question

I want to create a simple 4 row grit with susy, but recently i'm not able to get this working. I created the problem in Sassmeister: Link to problem in Sassmeister

Is there something i miss here?

Answer 1

Add …

  &:last-child {
    @include last();
  }

… below article. This will result in the last (4th) article not having a margin-right and hence it will fit in the row.
