EA Post Grid on tablet

I was trying some new designs for my client and noticed that if you put EA Post Grid, 1 post per page in Single column it looks messed up on Tablet. Looks awesome in mobile and desktop but it can’t be resize in tablet mode, looks small with a lot of empty space around. It’s Colormag free theme, don’t have any finished page ‘cos I am just looking for a new design. I made a screenshot, here is the file on WeTransfer https://we.tl/t-QPe8hrqczA
