Navbar Help with Portfolio Website

I’m trying to create a navbar like the one on the freecodecamp portfolio page project. It basically is a navbar you can click on and it takes you to a section of the page specified. As you scroll down the page it knows what section you are currently viewing and highlights on in the navbar, I really need help with this, and appreciate responses :slight_smile:
