I have made a simple background in Figma (1920×1600) and I want to place it as a hero image. But the problem is that the screen resolution can be 1920×800. I also want to place some content on the page. I want when user scrolls down the background would scroll until 1600 height and then it would scroll only the content.
Here’s the simple example:
I have an image from Figma image
then I import it as PNG export output

I wrote a CSS script to use it as a background:

body {
  overflow-y: hidden;
  margin: 0;
}

.background_container {
  background-color: #444444;
  background-image: url("https://i.sstatic.net/mL8LVRMD.png");
  width: 100vw;
  height: 100vh;
  z-index: -1;
  background-repeat: no-repeat;
  background-size: 100% auto;
  position: absolute;
}

<html lang="en">

This is the closest I could do… hope it helped you.
(make full screen to see the result)

    document.addEventListener('scroll', () => {
      const backgroundContainer = document.querySelector('.background_container');
      const scrollTop = window.pageYOffset;
      const maxScroll =1600-window.innerHeight;

      if (scrollTop <= maxScroll) {
        backgroundContainer.style.transform = `translateY(${scrollTop}px)`;
      } else {
        backgroundContainer.style.transform = `translateY(${maxScroll}px)`;
      }
    });

  body {
  margin: 0;
  padding: 0;
  overflow-x: hidden; 
}

.background_container {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 1600px; 
  background-image: url("https://i.sstatic.net/mL8LVRMD.png");
  background-size: cover;
  background-repeat: no-repeat;
  background-position: center;
  z-index: -1;
}

.content {
  position: relative;
  z-index: 1;
}
