MyTeam Multi-Page Website using NextJS, Styled-Components, GSAP

Hey everyone,

I've used NextJS, Styled-components, and a little bit of GSAP (first time using it) to make this site. (The screenshot looks a little weird due to the animations playing).

Any general feedback would be appreciated, but would specifically appreciate feedback on:

1. General code organization (any tips on how to make the CSS cleaner, and how to better organize React code).
2. Feedback on how I've created the general layout - this was a CSS-heavy website so I'm sure there are plenty of ways I could've improved the code.
3. Feedback on the navigation component - I split the component into two separate components (mobile and desktop) but I assume there is a cleaner way to do this.

I also see I have a few accessibility / HTML issues which I will clean up soon.

Any other comments would be appreciated as this is the hardest challenge I have done so far on the site :)
