Modal question

I have two rows of four staff photos. I want to place a modal for each photo so that a staff member description pops up. This works great in XS (8 photos directly underneath each other). However, when i move to breakpoint S (four rows of two photos), and M and L (two rows of four photos), the modal pushes the next column over and messes up the row. Any suggestions? Thanks!

Can you post a screen shot?
