CSS Scroll-Driven Animations: The Future of Interactive Web

Scroll-driven animations are now possible with pure CSS, eliminating the need for JavaScript libraries and improving performance.

What Are Scroll-Driven Animations?

Animations that respond to scroll position, creating parallax effects, progress indicators, and reveal animations natively in CSS.

Basic Syntax

@keyframes fade-in {
  from { opacity: 0; transform: translateY(20px); }
  to { opacity: 1; transform: translateY(0); }
}
.element {
  animation: fade-in linear;
  animation-timeline: view();
  animation-range: entry 0% cover 30%;
}

Real-World Examples

Progress Indicator

.progress-bar {
  animation: grow linear;
  animation-timeline: scroll(root);
}
@keyframes grow {
  from { scaleX: 0; }
  to { scaleX: 1; }
}

Parallax Effect

.parallax {
  animation: parallax linear;
  animation-timeline: view();
}
@keyframes parallax {
  to { transform: translateY(-50px); }
}

Browser Support

Currently supported in Chrome 115+, coming to other browsers. Use feature detection:

@supports (animation-timeline: scroll()) {
  /<em> Scroll-driven animations </em>/
}
