## JavaScript

/* No JavaScript — pure CSS; all designs for this title are driven entirely by the css field. */
```

How this works

A skewed ::before panel scaled scaleX(0) from the centre sweeps to full (overshooting width to cover the skewed corners); the label colour transitions once covered.

Make it yours

  • Change the blade angle via skewX.
  • Recolour the shutter and label.
  • Sweep from a side by moving origin.
  • Speed the sweep.

Gotchas — read before shipping

  • Scale wider than the button so corners don't gap.
  • Delay the label swap.
  • overflow:hidden clips the panel.

Skew + scale are universal; without CSS a solid CTA.
