Responsive Cards using CSS Flexbox & Media Queries

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

Im proud of getting the flex boxes right, I learned a lot about them through this project.

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

Initially, I struggled to get the two center cards to be stacked, but I took a break from this project & practiced flex boxes several times in other projects, & was able to come back & finish this easily.

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

As always, I'd like to know if there's anything I can improve on, anywhere I could simplify my code, etc.
