Neon Glow Tailwind Close Button

A neon tube that strikes on hover: the × idles as a dim, lightly glowing filament, then a ballast-misfire keyframe flickers it before three stacked drop-shadow() shells lock it at full glow. A blurred after: puddle brightens on the glass below. The port raises the idle state to a legible 3:1 — the original's resting × sat at 35% opacity and nearly vanished.

What changed in the port

Which parts became utilities, which stayed CSS, and why.

  • The resting filter: drop-shadow() became drop-shadow-[…]; the strike keyframes moved into @theme.
  • color-mix(in oklab, var(--neon) 60%, white) became a dedicated --color-tcb21-tube token.
  • UI upgrade from the CSS original: the idle × rose from 35% to 55% opacity with a brighter tube colour, lifting it from roughly 1.8:1 to above 3:1 so the button is identifiable before it is hovered; keyboard focus strikes the tube too.

How this works

Three shells make a tube. One drop-shadow is a halo; three at 2/6/14px read as a hot core, a bloom and ambient spill:

filter: drop-shadow(0 0 2px var(--color-tcb21-neon))
        drop-shadow(0 0 6px var(--color-tcb21-neon))
        drop-shadow(0 0 14px var(--color-tcb21-neon));

The strike is irregular opacity plateaus (8%, 11–18%, 21%, 24–30%) before settling at 55% — the misfire rhythm of a real ballast.

Make it yours

  • Colour: edit --color-tcb21-neon; every glow follows.
  • Always on: apply animate-tcb21-strike without the hover variant for a sign that lights on load.
  • Slower strike: 1.4s in the theme animation.

Gotchas — read before shipping

  • drop-shadow follows the painted shape; box-shadow would glow the square box instead of the ×.
  • Stacked filters are expensive on large areas; keep the glowing element small.
