CSS Scroll Snap Generator — Live Examples & Code

How CSS Scroll Snap Works

CSS scroll snap is controlled by three main properties: scroll-snap-type on the scroll container, scroll-snap-align on each snap target, and optionally scroll-snap-stop to prevent skipping.

/* Container */
.scroll-container {
  height: 100vh;
  overflow-y: scroll;
  scroll-snap-type: y mandatory; /* or: y proximity */
}

/* Each snap target */
.section {
  height: 100vh;
  scroll-snap-align: start; /* or: center, end */
}

/* Prevent skipping sections (optional) */
.section {
  scroll-snap-stop: always;
}

mandatory vs proximity

mandatory means the browser will always snap to a snap point after scrolling ends, regardless of where the scroll stopped. This creates a fullscreen-section feel; you can never rest between sections.

proximity means the browser only snaps if the final scroll position is close to a snap point (within about 50% of the snap target's size). The user can stop between sections if they scroll far enough from any snap point. Better for pages with long content.

scroll-snap-stop: always prevents the user from scrolling past a snap point in a single gesture, useful for step-by-step presentations where every section must be viewed.

CSS Scroll Snap vs fullPage.js

CSS scroll snap handles the basic snapping behavior. fullPage.js builds on top of that with keyboard navigation, mobile swipe gestures, animated transitions between sections, anchor links, and more.

For simple snap-to-section layouts, CSS is sufficient. For interactive presentations, marketing pages, or sites that need section transitions and full navigation control, fullPage.js saves significant development time.

Browser Support

CSS scroll snap is fully supported in all modern browsers (97.5% global coverage). fullPage.js goes further, compiled with Babel targeting IE 11, it works on virtually any browser your visitors might use.
