Origami Crease Close Button

A paper-craft ×: the two strokes are flat paper strips in 3D space (preserve-3d + perspective) that fold along their long axis on hover like creased origami, each half catching different light via a gradient that shifts mid-fold. Delicate, tactile, and entirely pseudo-element powered.

## JavaScript
```js
/* No JavaScript — perspective on the button + preserve-3d lets each bar rotateX along its own long axis, folding like creased paper. */
```

How this works

The button establishes perspective:400px; an inner span is the fold rig with transform-style:preserve-3d. Each stroke is a pseudo-element bar whose resting transform includes its 45° rotation; hover appends rotateX(58deg) — because the rotation happens after the 45° twist in the transform list, each bar folds along its OWN long axis, like a strip of paper creasing lengthwise.

Paper shading is a two-stop gradient down the bar's short axis (bright top half, shaded bottom half) whose contrast deepens on hover — the fold reads because the light changes, not just the geometry. A drop shadow beneath the rig sharpens as the strips lift toward the viewer.

Make it yours

  • Fold angle via --fold (58deg default; past ~75° the bars go visually paper-thin).
  • Warm or cool the paper with the two gradient stops.
  • Fold on :active instead of :hover for touch-first surfaces.
  • Slow to .5s and add a slight overshoot bezier for a more deliberate craft feel.

Gotchas — read before shipping

  • perspective must sit on the PARENT (button) — on the folding element itself you get flat scaling, no depth.
  • Keep backface-visibility default (visible) here — at 58° you never flip past 90°, and hiding backfaces causes pop-out if you increase the angle.
  • Don't animate the box-shadow with the fold on low-end targets — shadow blur repaints; the transform alone carries the effect.
