Group every 3 posts together in one class.

Hi there,

I would like to apply a class that contains every 3 posts. My goal is to pad the bottom of this class so that the posts float properly.

Right now everything displays how I want, but if in the future my client wants to edit/add a post, I want to ensure that the length of a single post doesn’t throw off the grid.

Links to helpful articles/tutorials are more than welcome.

Thanks
Rebecca
