How to block scroll?

Question

css

I know how to block the scroll. position: fixed;, but I need to make it possible to scroll the page. That is, there is a video tag and you need to make sure that I scroll the page and it scrolls as usual, while the video itself in the background was in one place.

Answer 1

If I understood everything correctly, then you need a video as a background?
