Responsive product card using CSS flexbox

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

The fact that I managed to build a responsive solution applying relative units

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

First of all, I didn't know anything about responsiveness so I looked up for it. Moreover, I had difficulties importing the font awesome icon. Other than that, I don't think there were any other challenges

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

I still don't think I have a full grasp of that responsiveness means. Therefore, I kindly ask you to check my work and my code to see if there is still something that I can improve/correct regarding this topic.
