Problem with navbar not centering

[NoahMK (Noah)]

Hello im having problems keeping the navbar centered in the same position for all pages, along with the home page not transitioning correctly on the top left logo.

I look it centered, however check that the ‘About us’ tab isn’t inside the div which contains the centered links when the screen is the biggest one.
