Background Cover Not Working on Samsung Internet

Hellow there!

I have a css code like this. It correctly works in desktop browsers and android browsers except samsung internet browser. I must make this works in all browsers. So anyone please help me.

.image-movie-fixed-01{
  Background-image: url(../img/01.jpg);
  Background-repeat: no-repeat;
  Background-position: center center;
  
  Background-attachment: fixed;
  Background-size: cover;
}

Solution

At present, you cannot.

According to CanIUse.com, the Samsung Internet browser, version 12.x, does not support background-attachment: fixed.

As for why it isn't supported, I speculate it's by-design:

I believe it's disabled to improve battery-life on browsers because fixed backgrounds are expensive to repaint when scrolling.
- iOS also didn't support background-attachment: fixed for the same reason:

  Fixed-backgrounds have huge repaint cost and decimate scrolling performance, which is, I believe, why it was disabled.
background-attachment: fixed dates back to CSS 1.0 in 1996. This is not a new feature that Samsung's developers simply haven't gotten around to implementing.
Samsung Internet is based on Chromium, so it inherits all of Chromium's features.
