Landing Animation Lab

Ten live demos of page-load, scroll, hover, and transition techniques — replay each effect, then read the exact code in three layers: CSS, Vanilla JS, and React + Framer Motion.

Page Load Reveal

Orchestrate a hero entrance with per-element delay — opacity + translateY via WAAPI, mimicking a landing page first paint.

Ship faster.

Build, deploy, iterate — all from one terminal.

Scroll Reveal

Cards fade and slide in when they enter the viewport — powered by IntersectionObserver with a threshold trigger.

Staggered Children

Animate a grid of items with incremental delay — adjust the stagger interval and replay to see the cascade effect.

Text Reveal

Split a heading into words and letters, then mask-reveal each character with a stagger — common hero headline technique.

Build Something Great

Scroll Parallax

Scroll inside the box — background layers move at different speeds via translate3d and a rAF-throttled scroll handler.

Scroll ↓ — layers move at 0.2× / 0.5× / 0.8×

Layered depth creates the illusion of space. Each layer translates proportional to scroll offset multiplied by its speed factor.

Keep parallax subtle — large offsets cause motion sickness and jank on low-end devices.

Prefer transform over top/margin to stay on the compositor thread.

End of scroll content — layers should have shifted noticeably by now.

Scroll Progress

A sticky progress bar fills as you scroll — uses CSS scroll-driven animation where supported, JS fallback otherwise.

0%

Scroll to watch the progress bar fill. The counter updates in sync with scroll position inside this container.

Scroll-driven animations tie keyframes directly to scroll progress — no scroll listeners needed in supporting browsers.

Pair with sticky positioning for reading-progress indicators, chapter markers, or timeline scrubbers.

Keep the sticky element lightweight — only animate transform and opacity for smooth 60 fps.

Almost there — the bar should be nearly full at this point.

End of content. Progress should read 100%.

Hover Micro-interactions

Pointer-driven polish — a magnetic button that follows the cursor, and a card that tilts in 3D toward your pointer.

Drag & Press

Pointer events drive a draggable chip with press-scale feedback and spring-back on release. Keyboard: focus the chip, use ← → to move.

Drag with pointer or use arrow keys when focused. Press scales down; release springs back.

Page Transition

Simulate route changes — crossfade + slide between two panels. Uses View Transitions API when available, WAAPI fallback otherwise.

Reduced Motion & Performance

Respect prefers-reduced-motion — swap elaborate motion for simple fades. Animate only transform and opacity when possible.

System: checking…

Compositor-friendly properties (transform, opacity) skip layout and paint — they run on the GPU thread. Avoid animating width, height, top, or margin in hot paths.
