## JavaScript
```js
/* No JavaScript — :focus-within lights each field, and an @property-driven conic-gradient (masked to a 1px rim) spins the refractive border around the active input. */
```

How this works

Each field wrapper uses :focus-within so the whole tile responds when its input gains focus. The glow is an animated conic-gradient border: a @property --angle typed custom property is spun with a keyframe, painted into a ::before that sits behind the input via a mask so only the 1px rim shows. The input itself is a frosted backdrop-filter tile with an inset top hairline.

Labels are real <label for> bindings and float above their fields. Because everything keys off native :focus-within, there's no JS and screen readers/keyboards work unchanged.

Make it yours

  • Recolour the travelling border by editing the conic-gradient stops.
  • Change spin speed via the lg-07-spin duration; slower reads calmer.
  • Adjust frost with the input's backdrop blur.
  • Turn the glow into a static ring by removing the animation and keeping the gradient.

Gotchas — read before shipping

  • @property is what makes the angle animatable — without it the conic border can't tween; a static gradient is the fallback.
  • Keep the mask so the gradient only shows as a rim, not a filled box behind the text.
  • Maintain input text contrast against the frosted tile for WCAG.

Floor set by oklch(), color-mix(), backdrop-filter, @property as this demo is written. The core technique itself goes back further — Chrome 85+ (@property).

@property animates the border; where unsupported the field shows a solid glowing ring on focus — same affordance, no spin.
