How can you be able to run a background video in html file?

Question

Yes I do want some content in front of the video

Answer 1

What do you mean by "background video"? Do you want some content infront of the video?

Do you want to hear the audio but not see any of the video?

Have you tried a video tag like this?

If you want HTML content overlapping the video, some CSS would help. Using position: fixed for your foreground content and setting top, left, bottom, right should do the trick.

Answer 2

You can use embbed video tag.
<video src="path/music.mp3 autoplay repeat><source type="type" src="file.type"></video>

Then just add hidden attribute.

style="visibility:hidden;"
