The nav menu on the site displays perfectly on large screens, but on smaller displays including ipad landscape, it’s not quite right on the bottom - It’s as if there’s too many nav links on the menu so what needs to be done I guess is to squash the nav links together a bit on smaller displays.
I would suggest making top and bottom padding for the nav links equal 1.2 vw (in the desktop mode). Then it will depend on screen size and will shrink a bit for the iPad landscape.
