Four Card Feature Challenge

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

With each attempt I work from a mobile workflow first. Right now I'm doing a lot of changing back and forth due to not thinking about the media query changes needed to take a desktop design and move it into mobile.

I lay out the mobile design, see what it looks like in desktop, re-arrange for desktop, and then set my media query.

I'm not sure if this is a best practice or not.

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

some flexbox issues with the column which has two cards.
