How do I override Bootstrap styles like nav link font color?

My codepen:

I’ve been trying to find the right selector to change my navbar link styles for about two days now… I’m able to change the color in Inspector, where I found Bootstrap’s simple declaration a {…}. However, copying the selector doesn’t work and neither does all the options I’ve tried so far. Is this a Codepen issue? I’ve never used it before now.

Your CSS for .navbar has a missing }

Good catch, thank you!

your nav bar is breaking while i scroll the mouse.
