Responsive social link page with keyboard navigation

What are you most proud of, and what would you do differently next time?

Hello, in this challenge, I want to highlight the navigation feature between each link button. I'm using javascript to enable user to navigate between each social link button with this condition :

1. If cursor is not hovering on any link button, user will able to navigate between link button using keyboard (arrow up or arrow down).
2. If cursor hovering on any link button, user will not able to navigate between each link button.

What challenges did you encounter, and how did you overcome them?

The most challenges for me are:

1. Since I'm not upgrade my account to pro yet, I'm not able to see the full design of this challenge, so I expected to have some different final layout.
2. In my navigation javascript, I'm still figuring out on how to able user to navigate between link button when cursor is hovering on any link button but the styling is not overlap each other ( I mean the text color on hover and on navigate).

What specific areas of your project would you like help with?

Please give any feedbacks on my solutions. Thank you guys.
