`The background video is not being displayed on the transparent PNG`

I have created a transparent PNG image featuring a theater setup and I am attempting to overlay a 1-second video as a background element, similar to a GIF. However, when I try to display the video, instead of seeing it, the background color appears. Additionally, setting the z-index lower than other elements does not seem to solve the issue. Interestingly, removing the video using the inspect element tool reveals that it is indeed present.

It's worth noting that this example is just a demonstration to highlight the problem at hand.

<div id="bg" style='position:absolute;z-index:0;left:0;top:0;width:100%;height:100%'>
<img style='width:100%;height:100%;' alt='[]' src="http://www.moviebowlgrille.com/img/nav/rental.png">
<video style='width:100%;height:100%;' alt='[]' autoplay loop>
<source src="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" type="video/mp4" />

Answer №1

To achieve a transparent background for the video above, you must include the CSS declaration background-color: transparent. Additionally, using the CSS declaration position: absolute will allow you to position both the image and video on top. Therefore, the complete CSS rule would be as follows: 

img {position: absolute; background-color: transparent;}
Keep in mind that the rules assigned to #bg may not be necessary.

I trust this information has been helpful to you.

img {
  position: absolute;
  background-color: transparent;
}
<div id="bg" style='position:absolute;z-index:0;left:0;top:0;width:100%;height:100%'>
<img style='width:100%;height:100%;' alt='[]' src="http://www.moviebowlgrille.com/img/nav/rental.png">
<video style='width:100%;height:100%;' alt='[]' autoplay loop>
<source src="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" type="video/mp4" />

Answer №2

If you have access to video editing software, consider enhancing your content by overlaying a PNG file onto your video. This method requires less technical knowledge and can make it easier for your website host to manage your site efficiently.
