Grid not adapting to CMS content

I’m working on a store for a client, I’ve added a CMS blog. This blog is arranged by a three column gird but if the amount of articles added is not an even number or exactly 6, they arrange incorrectly on the grid… How can I make the grid fill up correctly…? Please help!
