Hiding search bar on mobile device cause background image not to fully stretch and creating white stripe at the bottom

Issue

I know this problem is common and plenty of users have asked there for a solution and of course, I did read answers to these questions but nothing has helped for me.

This is how does the website look like when it is first rendered. All things are working just fine, the image is covering the whole page.

enter image description here

Then I try to scroll down and with an approximately 50% chance this is happening.
enter image description here

The scrollbar is hidden but the ugly white stripe appears at the bottom. When I stop scrolling the image stretches itself to the proper position. But the scrolling experience is ruined because of that white stripe.

Any helping hands for this?

<div className="flex" style={{height: height, minHeight: "576px" }}>
  ....
</div>
html { 
background: url(./bg.jpg) no-repeat center center fixed; 
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;}

Please check this second attempt:

(or a preview link that will eventually expire:
https://cdpn.io/pen/debug/NWXVvbL?authentication_hash=wQMPobNYVpdk )

the change is how the background image is added:

body:before {
  content: "";
  display: block;
  position: fixed;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
  z-index: -10;
  background: url(./bg.jpg)
    no-repeat center center;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

background: fixed no repeat not working on mobile

Please note that my original solution below isn’t a good solution because of how mobile devices handle fixed background images.

How does this look for you?

It’s forcing the HTML element to be 100vh. For illustration, I removed the styling on your .flex class, it’s not needed to solve your image background question.

And I also added a viewport meta tag to the head of the page

<meta name="viewport" content="width=device-width, initial-scale=1">

HTML

<div class="flex">
  ...
</div>

CSS

 html {
  background: url(./bg.jpg) no-repeat center center fixed;
    no-repeat center center fixed;

  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
height: 100vh; /* NEW */
}

/* .flex styling removed */
/* .flex{
  height: height, minHeight: "576px";
 
} */
