Fylo landing with scss, grid, cool hover/focus effects

Another great job Roman. The nav link CSS transitions are really cool and the mobile implementation is awesome. I did find some things that can be improved:

• The style guide calls for the max-width for desktop to be 1440px. Yours is set at 1170px. This causes the site to look thinner and the columns to not match the design.
• All of your headings are using the wrong font. They should be using var(--ff-heading) instead of var(--ff-body)
• The Stay productive, wherever you are seems to be incomplete on desktop. The heading is small and not vertically aligned to the section.
• The Get early access today CTA container is too thin. It causes the content to feel squished in, but it also doesn't match the design specs.
• I like the sticky header, but the transition is wonky. It looks like it's growing then shrinking. When you scroll back up and the sticky header is removed, it jumps a few times before it's removed. I would like to see this get smoothened out.
• Fixing the button :hover transition would be nice too. A nice smooth gradient transition would make this implementation even better.

I can only say WOW WOW, man; keep it up. Any points to learn animations on JS?
