Scroll Animations

Q: What is the purpose of using IntersectionObserver in scroll animations?

Use IntersectionObserver; avoid scroll listeners with reflow. Animate opacity/transform only. Debounce counters and heavy effects.

Q: How should I handle reduced motion settings on small screens to ensure accessibility?

Reduce motion on small screens; avoid horizontal parallax. Keep text legible during animation; ensure tap targets remain stable.

Use scroll-triggered animations to guide attention without hurting performance

Animate elements to reinforce the visual hierarchy and reveal content gradually. Avoid creating distracting parallax effects; keep motion subtle and purposeful.

Fade/slide-in on viewport entry with a threshold (~20–30%)

Parallax scrolling is acceptable when applied to background images at low amplitudes, ensuring smooth transitions without significant performance impact.

Counter animations for numbers with an upper time cap (<1.2s)

When using counter animations for numerical data, adhere to a maximum execution time of 1.2 seconds to maintain responsiveness and avoid overwhelming the user's experience.
