Responsive card component using React JS

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

I'm proud of working on my second react and being able to overcome the obstacles I faced.

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

I faced a challenge when I wanted to change my image from mobile-desktop depending on what the screensize was, and I also faced a challenge during deployment to GitHub. I was greeted with an Error 404 and was able to fix it after several hours of combing the web. I am particularly glad to be able to learn this way.

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

I would like help with the dos and donts of React, the best workflow for working with React (if any) and any tip in general about development. Thank you very much.
