CSS Skew Shake Animation

Skew is the shake that deforms: a jelly sticker that wobbles like gelatin when hovered (skewX oscillating around a bottom anchor), and a racing 'speed shiver' banner where a hard forward lean plus micro-skew jitter makes a static element look like it's doing 200km/h.

## JavaScript
```js
/* No JavaScript — the sticker skews around its planted bottom edge (with a whisper of scaleY for volume), while the text runs a counter-skew at ~40% amplitude so the words wobble WITH the jelly yet stay legible. */

/* No JavaScript — the wrapper holds a constant skewX(-8deg) posture while the banner runs a 20Hz steps(2) skew jitter, and background speed-lines rush past on a linear loop. Static pixels, kinetic story. */
```

How this works

translate moves an element; skew bends it. Anchor the deformation with transform-origin at the bottom and the top swings while the base stays planted — instant jelly:

.jelly:hover{
  transform-origin:50% 100%;
  animation:wobble .8s cubic-bezier(.36,.07,.19,.97);
}
@keyframes wobble{
  15%{transform:skewX(-12deg)} 30%{transform:skewX(9deg)}
  45%{transform:skewX(-6deg)}  60%{transform:skewX(4deg)}
  75%{transform:skewX(-2deg)}  90%{transform:skewX(1deg)}
}

Decay matters double here — jelly loses energy fast. The speed variant is the opposite temperament: a constant skewX(-8deg) lean (posture, via a separate wrapper) plus a ±1.5deg high-frequency skew jitter (turbulence). Lean on one element, jitter on another — composed transforms without conflict.

Make it yours

  • Jelly: first swing 10–14°, decay hard; anything past 16° shears text illegibly.
  • Counter-skew inner text (skewX(+4deg) inside a -8deg parent) to keep glyphs closer to upright.
  • Speed shiver: lean 6–10°, jitter ±1–2° at 15–25Hz via steps — more jitter than that smears.
  • Jelly duration .7–.9s; gelatin is slower than error shakes.

Gotchas — read before shipping

  • Skew visually shifts baselines — center the jelly's content optically, not geometrically.
  • skew + border-radius warps corners non-uniformly; chunky radii read as melting (sometimes desirable, know it's coming).
  • Don't skew form controls — carets and selection rectangles don't follow the shear in all engines.
  • Extreme skew inflates the paint area (the bounding box grows) — keep shivering elements reasonably sized.

Floor set by oklch() as this demo is written. The core technique itself goes back further — Chrome all modern.

skew() inside transform is CSS3-transforms baseline — works everywhere, including the counter-skew composition trick.
