Best Practices
Container Setup:
✓ Set overflow direction
✓ Choose mandatory vs proximity
✓ Add scroll-padding for fixed elements
✓ Consider scroll-behavior
Item Setup:
✓ Define flex/grid sizing
✓ Set scroll-snap-align
✓ Use scroll-snap-stop for important items
✓ Add scroll-margin if needed
UX Considerations:
✓ Proximity for optional snapping
✓ Mandatory for full-page sections
✓ Test with keyboard/touch
✓ Respect reduced motion
Avoid:
✗ Snapping on large content areas
✗ Missing overflow settings
✗ Ignoring accessibility
✗ Mandatory snap on long content
Conclusion
CSS scroll snap creates intuitive, native-feeling scroll experiences without JavaScript. Use scroll-snap-type on containers with mandatory for strict snapping or proximity for gentle guidance. Apply scroll-snap-align to children to define snap points. Combine with scroll-padding for fixed headers and scroll-snap-stop to ensure important content isn't skipped. Always respect user motion preferences and ensure keyboard accessibility.
