Responsive solution with media queries

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

I tried everything to make it responsive without media queries. I couldn't. But the result looks good anyways.

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

Positioning the elements so they don't look bad when the screen starts getting small, I just thought about how many columns should it have and how many of them would the elements cover.

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

Is it possible to make this without media queries? (I don't think so, but if you somehow find a way, please tell me.)
