Social Links Profile using flexbox

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

Along the way of doing this project, I learnt a bit more about other CSS selectors that I implemented in setting the font-weight of all the span elements, except for one as shown in the CSS snippet below.

span:not(.small-description){
    font-weight: 600;
}

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

With this project, I challenged myself to use the px measurement as little as possible, opting instead for relative units for margin, padding, font-size, etc. Rem and em were measurements I had not fully grasped before, but I now have a better understanding of their usage.

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

Any feedback, tips or tricks would be greatly appreciated.
