My responsive solution to "Social Links Profile"

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

I'm quite happy to have managed to make everything as responsive as possible. This is my first contribution, I'm still getting started.

UPDATE : I readjusted the elements to better fit the model.

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

The positioning gave me a hard time. But it gave me a better understanding of Flex and Grid.
