Avoid scrolljacking and custom scroll behavior

Scrolljacking breaks user expectations, interferes with assistive technologies, and creates unpredictable experiences that frustrate users with motor impairments or cognitive disabilities.

Quick Reference

• Never override native scroll speed or direction
• Avoid scroll-triggered navigation (one page per scroll)
• Scrolljacking breaks assistive technologies and user expectations
• If custom scrolling is essential, provide a way to disable it

Check

Test scrolling behavior and verify it feels native. Check that scroll speed is not modified, scroll direction is not inverted, and scroll events are not hijacked for animations or navigation without user consent.

Fix

Remove JavaScript that overrides default scroll behavior. If custom scrolling is essential, respect prefers-reduced-motion and provide a way to disable custom scroll effects.
