Removing gaps between images on project page

Hello!

My website is www.othi.la 

I have had no luck trying to use CSS to remove the gaps between the images in each one of my project pages.

Attaching an example -- you can see how there's a small gap between the two images (that example is from this specific project page: https://www.othi.la/work-1/dilatechnologies)

Thanks!

The gap between the images is a product of the grid spacing, if you go into the section settings and reduce the row gap to zero then the blocks will butt up to each other without a gap.

Oh! Thank you Ziggy!
