Struggling to fix my Navbar and video. Please help me

Hello, I need some help with my Product Landing Page navbar and video. I can figure out how to arrange my navbar properly and for some reason my video cannot connect. im not sure if this is a problem with my own laptop or what.Project Landing Page
Thank you

As for youtube - your URL for the video is not correct for embedding. I think that’s the only error. Just copy the code youtube gives you and it will load.

I think the youtube link is broken, And if you want to use a sticky header/nav bar(with position=fixed || absolute) style the elements to display inline and have a solid BG color

Do you know if there is anything in particular I need to change about my code for the display: inline to work? I’ve put it in but it’s not working.
