I completed the landing page project, it seems passed the test but there is a problem on page. As you can see, I added a form, video etc. but can’t see them. If I remove fixed position from nav-bar ID, it’s fixing but then I can’t pass test because of viewport problem.
I’m trying to add margin but nothing happens. I don’t know what’s wrong but even background color didn’t change. Literally, after using “position: fixed”, my other codes doesn’t work
