Generated CSS

/* CSS Scroll-Driven Animations */

@keyframes scroll-animation-1 {
  from { opacity: 0; }
  to { opacity: 1; }
}

.fade-element {
  animation: scroll-animation-1 linear;
  animation-timeline: view();
  animation-range: entry 0% cover 30%;
}

/* Fallback for browsers without scroll-timeline support */
@supports not (animation-timeline: scroll()) {
  .fade-element {
    opacity: 0;
    transition: opacity 0.3s ease;
  }
}

/*
JavaScript Fallback (works in all browsers):

const scrollContainer = document.querySelector('.scroll-container');
const handleScroll = () => {
  const scrollTop = scrollContainer.scrollTop;
  const scrollHeight = scrollContainer.scrollHeight - scrollContainer.clientHeight;
  const progress = Math.min(scrollTop / scrollHeight, 1);

  // Fade In
  const fadeelementElement = document.querySelector('.fade-element');
};
scrollContainer.addEventListener('scroll', handleScroll);
*/

How to Use:

  1. 1. Copy the generated CSS above
  2. 2. Add it to your stylesheet
  3. 3. Apply the CSS classes to your HTML elements
  4. 4. Ensure your page has sufficient scroll height
  5. 5. Test in Chrome 115+ or other Chromium browsers

Example HTML:

<div class="fade-element">
  This will fade in on scroll
</div>
<div class="scale-element">
  This will scale on scroll
</div>
<div class="progress-bar">
  Progress indicator
</div>
