- Increase --focus-scale from 8 to 9 — at scale 8 the card matched the viewport width exactly (240×8=1920), leaving zero tolerance for subpixel rounding. Scale 9 overshoots by 240px on each axis. - Reduce grid gap from 40px to 24px — the 1040px grid in a 1080px viewport left only 20px of padding, causing bottom-row cards and their box-shadows to clip at the frame edge. - Remove transform-style: preserve-3d from both snippets — no 3D transforms are used, and preserve-3d can cause compositing artifacts with overflow: hidden ancestors. - Unzoom: set --pu-sibling-fade to 0 and drive sibling opacity via GSAP (starting at t=2.0s). Previously, CSS-driven opacity made cards 70% visible when they first peeked into the viewport, creating colored strips at the frame edge during the reveal.

Parallax Unzoom — focus card scales down from full frame while siblings
|
||
parallax IN to form a grid. The reverse of parallax-zoom.
|
||
|
||
Pairs naturally with parallax-zoom: zoom INTO a card in scene 1, then
|
||
unzoom OUT of it in scene 2 to reveal a fresh grid underneath.
|
||
|
||
Usage:
|
||
1. Wrap your card grid with class="parallax-unzoom-grid".
|
||
2. Mark each card with class="parallax-unzoom-card".
|
||
3. Add data-pu-row="0|1|2|..." and data-pu-col="0|1|2|..." per card.
|
||
4. Mark the card that starts at full size with data-pu-focus="true".
|
||
5. Drive --pu-progress 0 → 1 on the .parallax-unzoom-grid from your
|
||
composition's paused GSAP timeline (see example at bottom).
|
||
|
||
Tunable CSS variables on .parallax-unzoom-grid:
|
||
- --pu-focus-scale (default 6) starting scale of the focus card
|
||
- --pu-sibling-push (default 900px) outward distance siblings start at
|
||
- --pu-sibling-fade (default 1) sibling opacity falloff (0–1)

// Scene 2 (3-6s): unzoom OUT of a NEW grid via parallax-unzoom,
