Tilt parallax card

A layered 3D card response that moves foreground content slightly more than its surface.

CSS transformpointer3D

[data-sc-effect="tilt-parallax-card"] { perspective: 900px; }
[data-sc-effect="tilt-parallax-card"] .sc-tilt-surface { transform: rotateX(var(--sc-rotate-x, 0deg)) rotateY(var(--sc-rotate-y, 0deg)); transition: transform 180ms ease; transform-style: preserve-3d; }
[data-sc-effect="tilt-parallax-card"] .sc-tilt-foreground { transform: translateZ(22px); }
@media (prefers-reduced-motion: reduce) { [data-sc-effect="tilt-parallax-card"] .sc-tilt-surface { transform: none; transition: none; } }

const tiltCards = document.querySelectorAll('[data-sc-effect="tilt-parallax-card"]');
tiltCards.forEach((card) => { const surface = card.querySelector('.sc-tilt-surface'); card.addEventListener('pointermove', (event) => { const box = card.getBoundingClientRect(); const x = (event.clientX - box.left) / box.width - .5; const y = (event.clientY - box.top) / box.height - .5; surface.style.setProperty('--sc-rotate-x', `${y * -8}deg`); surface.style.setProperty('--sc-rotate-y', `${x * 10}deg`); }); card.addEventListener('pointerleave', () => { surface.style.setProperty('--sc-rotate-x', '0deg'); surface.style.setProperty('--sc-rotate-y', '0deg'); }); });

Native recipes

Small, composable patterns you can paste into a plain HTML site, a CMS, or a generated staging build.

Card stack shuffle

Cycle a small stack of cards with explicit controls and a natural static order.

Testimonials, team highlights, and compact product feature stacks.

[data-sc-effect="card-stack"] { position: relative; display: grid; }
[data-sc-effect="card-stack"] > * { grid-area: 1 / 1; transition: transform 300ms ease, opacity 300ms ease; }
[data-sc-effect="card-stack"] > *:nth-child(2) { transform: translate(8px, 7px) scale(.96); opacity: .7; }
[data-sc-effect="card-stack"] > *:nth-child(3) { transform: translate(16px, 14px) scale(.92); opacity: .45; }
@media (prefers-reduced-motion: reduce) { [data-sc-effect="card-stack"] > * { transition: none; } }

Perspective grid

Create a subtle perspective grid that shifts with a pointer while staying entirely CSS-based.

Tech hero panels, dashboards, and creative landing-page backgrounds.

[data-sc-effect="perspective-grid"] { --sc-grid-x: 0px; --sc-grid-y: 0px; position: relative; overflow: hidden; background: #111827; }
[data-sc-effect="perspective-grid"]::before { content: ""; position: absolute; inset: -35%; background-image: linear-gradient(rgba(148,163,184,.25) 1px, transparent 1px), linear-gradient(90deg, rgba(148,163,184,.25) 1px, transparent 1px); background-size: 28px 28px; transform: perspective(260px) rotateX(54deg) translate(var(--sc-grid-x), var(--sc-grid-y)); transform-origin: center bottom; pointer-events: none; }
@media (prefers-reduced-motion: reduce) { [data-sc-effect="perspective-grid"]::before { transform: perspective(260px) rotateX(54deg); } }

const grid = document.querySelector('[data-sc-effect="perspective-grid"]');
grid.addEventListener('pointermove', (event) => { const box = grid.getBoundingClientRect(); grid.style.setProperty('--sc-grid-x', `${(event.clientX - box.left - box.width / 2) * .08}px`); grid.style.setProperty('--sc-grid-y', `${(event.clientY - box.top - box.height / 2) * .04}px`); });

Bring a library when it earns its weight

Free library starters

Version-pinned starting points for open-source libraries. Review the license and performance tradeoff before adding another dependency.

For GPTs and other agents

Tell the LLM how to use the library.

Give the model a clear selection loop. It should discover, fetch, compose, then explain where it placed the effect instead of inventing a new dependency.

Recommended instruction

Use this in a system or developer prompt when the model can access the REST API or MCP.

When a user asks for website motion or an interaction effect:
1. Search PocketPapi’s effects catalog before writing a new animation.
2. Prefer a native recipe when it meets the request; use a free MIT library only when it materially reduces complexity.
3. Fetch the chosen effect by effect_id and inspect its reduced-motion and accessibility notes.
4. Compose the effect for the user’s real selector. Keep the selector scoped and do not rewrite unrelated styles.
5. Return the exact files or insertion points, explain the dependency (if any), and mention keyboard, touch, and prefers-reduced-motion behavior.
6. Never add a library from an untrusted CDN or use a versionless URL when a pinned URL is available.

Use the PocketPapi tools `sitecommander_effects_search`, `sitecommander_effects_fetch`, and `sitecommander_effects_compose` for this workflow.

No command center required.The catalog is public and read-only. Use the REST endpoints from any site or connect the bearer-authenticated MCP endpoint to an agent.
