No, neither of these questions is solved.
The code you referred to made the main navigation slightly smaller.
There is still a black background to the dropdown menu when viewing the homepage on a desktop as per the image attached above.
And the dropdown menu text size is still too large on mobile, see other image attached above. More specifically if you click on 'Work', the sub menu item 'Some place, no place' is split over 2 lines, I would like it all to fit on one line.
Thanks
