Responsive social-links-profile card

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

I think my understanding of the CSS has improved a bit.

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

I encountered the challenge of min-width and max-width while making the design responsive. However both of them have been sorted.

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

Please someone tell me that the code written by me for this design is correct and if it correct how can I improve? Suggest better ways to make the design responsive.
