## JavaScript
```js
/* No JavaScript — a registered @property --angle spins a conic-gradient border on :hover. */
```

How this works

A registered @property --angle (typed <angle>) drives a conic-gradient painted on a ::before that sits just behind the card as its 'border'; animating --angle from 0 to 360° spins the gradient. A blurred copy on ::after throws the same gradient as an outer glow.

At rest the border is dim; on hover the animation runs and the glow's opacity rises, so the outline lights up and rotates. The card face itself stays a solid dark panel above both layers.

Make it yours

  • Set the neon hues in the conic-gradient stops — dual-tone (cyan/magenta) or a full spectrum sweep.
  • Speed or stop the rotation with the --angle animation duration.
  • Thicken the border by increasing the ::before inset offset.
  • Make it always-on (not hover-gated) for a permanent lit-frame card.

Gotchas — read before shipping

  • Animating a custom property requires it be registered with @property and a typed syntax — a plain --angle won't interpolate.
  • Keep the card face fully opaque above the gradient layers or the border colour bleeds through the content.
  • A spinning gradient plus blur is paint-heavy — reserve it for one or two feature cards, not a whole grid.

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

@property-driven conic-gradient animation: Chrome 85+, Safari 16.4+, Firefox 128+. Without @property the border shows a static gradient.
