Responsive 3 card column with Flexbox

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

I am most proud of my progress with doing these challenges. This took me less than an hour to do whereas before I might have spent 2 hours on a simple design.

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

One challenge I encountered was getting the sizing of the cards on smaller screens to be contained within the padding on the body. Turns out giving the body a min-height: 100vh instead of height: 100vh did the trick.

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

Any feedback is appreciated!
