Good job on the code you wrote especially since it is quite involved! I think you made this pull request before I commited my changes, so could you get my changes and make that match the Figma design?
To be more specific, I changed the layout of the website so that the navBar and the padding on the top would match the design. This changed made the page I was working on match the design which you can see on the first image, but the others look a little off as you can see on the second and third images. So could you make these match the design?

+1 to Charlie's comments? Could you make style changes to match the Figma? You could also send screenshots to the designers to get feedback from them as well
