My codepen:
Your code is failing the user story #1 (The navbar should always be at the top of the viewport. ). The reason for the error is that you have ‘top: 10px;’ in #navbar css. change it to ‘top: 0;’ and it should pass all the tests.

As for the video it’s better to copy the embedded code directly from the youtube video and pasting it.
add the video again and don’t remove anything
<iframe width="560" height="315" src="https://www.youtube.com/embed/4Eiohy-9YwM" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
i hope that help’s you
If you want a better way to add youtube videos, you should try this technique.
