Four Card Solution - Help Wanted

What are you most proud of, and what would you do differently next time?

I'm glad that I came back to this after taking some time away. Still, I am having trouble with the code.

What challenges did you encounter, and how did you overcome them?

I had limited experience with the different display functions in CSS, so I learned a lot more about them and practiced with some online courses/ games. Unfortunately, I'm still having issues with the display.

What specific areas of your project would you like help with?

I would really appreciate if anyone can help with why my @media command isn't changing the layout the way I've intended it to. I've spent a lot of time looking at it and trying different tweaks to no avail.
