Social Links Profile using BEM

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

1. Is my usage of px, rem, and em correct? I have only used rem and px throughout my code because I couldn't find a suitable place for em. If you have any suggestions on where I can use each of these units better, I would love to know.
2. Is my responsiveness good and is everything up to scale depending on the font size and zoom of the browser? Any areas of improvement regarding responsiveness?

• Is there a better way to make the padding responsive depending on the screen size? I used padding: clamp(1.5rem, 4vw, 2.4rem); Not sure if that is the best method.
