I want a video overlay over my website. Imagine leaves falling from the top to the bottom of the screen, while still having the website visible behind the leaves. The idea was to create a video with a transparent background and overlay it. I’ve played around with many different options, none of which seem to work. The website does not need to be intractable while the video is playing I just need it to be visible on the other side. Any recommendations of doing this while keeping high compatibility?
