Challenge: Product Landing Page - Build a Product Landing Page

Link to the challenge:

Hello there.

Do you have a question?

If so, please edit your post to include it in the Tell us what’s happening section.

Learning to describe problems is hard, but it is an important part of learning how to code.

Also, the more information you give us, the more likely we are to be able to help.

Your #nav-bar should always be at the top of the viewport.
The solution doesn’t work for me please.
