Navbar can show the active page

[Owen-Jiang]

Is your feature request related to a problem? Please describe.
The navbar does not bold the page that the user is on.

Describe the solution you'd like
The navbar should show the current page as a bold or differently-colored word or text.

Describe alternatives you've considered
Not doing this would be annoying, and I have tried to get it to work in the past. I'll have to take another crack at it.

Additional context
None
