How do I make the nav bar extend the length of page?

When I make it full screen the nav bar only takes up about half the page.

What do you mean? I can see the navbar which takes the full height of the page.

I guess I meant like evenly spaced out, there’s a big empty gap under conclusion.

Im not an expert… but maybe you can change the fontsize to take some more space. I see that the size of your navbar text is smaller than the rest of the text on the project. Maybe add some padding too
