Squarespace 7.1 Custom Image Block Grid

Site URL: https://virginsuncare.com/ingredients

I created this custom image block grid in Squarespace 7.1 to provide an interactive and detailed view of the ingredients while being able to see them as one working unit. I am having trouble aligning the bottom base line of these images. Is there anyway to center this grid or create a fixed bottom height for the block as a whole?

The blocks are currently sizing different and the bottom line changes at every screen size increment. I have been trying to figure this one out for weeks so any help or creative ideas would be appreciated.

Thanks!
