Frequently Asked Questions
What is CSS Scroll Snap and why should I use it?
CSS Scroll Snap is a native CSS feature that allows you to create controlled, snap-point-based scrolling experiences without any JavaScript. It's perfect for image galleries, onboarding flows, product showcases, article pagination, and fullscreen landing sections. Benefits include: native browser performance (GPU-accelerated), no JS overhead, accessibility-friendly, works with touch/trackpad/mouse wheel, and progressive enhancement — browsers that don't support it simply fall back to normal scrolling.
What's the difference between mandatory and proximity?
Mandatory — The browser always snaps to a snap point after scrolling stops, regardless of where the scroll momentum ends. This creates a strict, predictable experience. Best for: image galleries, slideshows, onboarding screens.

Proximity — The browser only snaps if the scroll position naturally lands near a snap point. If the user scrolls and stops far from any snap point, no snapping occurs — the content stays where it is. This feels less forced. Best for: article pagination, content sections where you want gentle guidance without restricting free scrolling.
What does scroll-snap-align control?
scroll-snap-align is set on child elements and determines where the snap point is located on each item.
  • start — Snaps the start edge of the child to the start edge of the container.
  • center — Snaps the center of the child to the center of the container. Great for centered carousels.
  • end — Snaps the end edge of the child to the end edge of the container.
  • none — No snap point on this element (useful for excluding certain items).
You can also set two values like scroll-snap-align: start center for block and inline directions separately.
How do scroll-padding and scroll-margin differ?
scroll-padding is set on the scroll container — it creates an offset inside the container that affects all snap points. Think of it as "inner padding" for snapping. Use it when you have a fixed header/navbar and want snap points to account for that space.

scroll-margin is set on individual child elements — it creates an outward offset for specific items' snap points. Use it when you want particular items to snap with extra spacing around them. Both properties accept length values (px, rem, %, vh, etc.) and can take up to 4 values for each side.
Browser compatibility: which browsers support Scroll Snap?
CSS Scroll Snap has excellent browser support (96%+ global coverage as of 2025). It's supported in all modern browsers: Chrome 69+, Firefox 68+, Safari 11+, Edge 79+, Opera 56+, and all Chromium-based browsers. iOS Safari has supported it since iOS 11. The only notable gap is Internet Explorer (which is end-of-life). On unsupported browsers, the scroll container simply behaves as a normal scrollable area — a clean, graceful degradation.
Why isn't scroll snapping working on my site?
Common troubleshooting checklist:
  1. Overflow is required — The container must have overflow: auto or overflow: scroll (not hidden, not visible) in the snapping direction.
  2. Content must overflow — If content fits entirely within the container, there's nothing to snap to.
  3. Correct property placement — scroll-snap-type goes on the container; scroll-snap-align goes on the children.
  4. Don't use on body/html — Applying to <html> or <body> can behave inconsistently; wrap content in a dedicated container div instead.
  5. Check for conflicting CSS — Properties like overflow: hidden on parent elements can break snap behavior.
Can I combine Scroll Snap with JavaScript for advanced interactions?
Absolutely! Scroll Snap works seamlessly with JavaScript. You can listen for scroll events to update UI indicators (like the dots in our preview above), trigger animations when a new section snaps into view using Intersection Observer, or programmatically scroll to specific snap points using element.scrollTo() with behavior: 'smooth'. Libraries like GSAP ScrollTrigger also integrate well with scroll snap for advanced scroll-driven animations.
What is scroll-snap-stop and when should I use it?
scroll-snap-stop controls whether the browser can skip over snap points during fast scrolling.
  • normal (default) — Fast scrolling may skip multiple snap points to reach the final resting position faster.
  • always — The browser is forced to stop at every snap point, even during rapid scrolling. This ensures users see every item but can feel restrictive.
Use always sparingly — it's best for critical content sequences (e.g., onboarding flows, legal disclaimers) where you must ensure each section is seen before proceeding.
