Grid column spacing - I can't figure it out

How can I make the column gapless or at least less of a gap?

Take out the margin-left and margin-right you have on .project-tile.

If you want to remove the space completely, then remove all the -gap styles you have on #projects.

Okay, I tried that and it removes some spacing. I think I need to be more specific, how can I make the images closer to each other? See how one stacks on top of the other closely.

Do you have a picture of what you want the final look to be like?

I switched over to flexbox and I’ve been able to achieve the look I wanted. Thanks.
