Social links profile with html5, css

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

I am proud of being able to achieve a very similar final look as the challenge and I believe I am getting better with measurings, like padding and margin. I feel like I could learn a more effective and clean way to develop.

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

I still get confused about what in flexbox does what but just by searching a bit I can easily get back on track.
