Yep your Background video needs 100vh but that doesn’t fix your overlapping issue from below.
- Take the nav bar out of the bg video section, put it above. There’s no need for it to be inside, unless you want it there.
- I would delete the background video layer, but keep all the other layers, and add the video again with these settings.
I did this for you in a video screencast. I couldn’t upload a video into the layer because it’s read-only:
When you add the overly use the background color instead and reduce the opacity. That should fill the entire div.
