Need Help Centering Icons

Hey everyone,

All of the centering methods I try aren’t working on the icons at the bottom of the page. It may look centered on full-screen but if you inspect and view the portfolio website at 320px then you can see that it is not centered.

Appreciate any help you can provide

UPDATE: It is centered at the full screen view, but I can’t get it to be centered at the 320px media query

I was using letter-spacing to get space between icons, should have been using paddding instead, now things are centered
