Tailwind Neon Text-Glow Utility

The Tailwind answer: a reusable neon-glow utility built with arbitrary text-shadow values and a tokenised drop-shadow scale, shown as the exact class string devs paste into a utility-first project — no custom CSS file needed.

## JavaScript
```js
/* No JavaScript — rendered Tailwind output; the annotation shows the source class. */
```

How this works

Tailwind can't express a five-layer neon text-shadow with stock utilities, so the pattern is an arbitrary value: [text-shadow:_0_0_10px_theme(colors.cyan.400)...] — or, cleaner, a single text-neon utility registered once in the config's addUtilities. This demo shows the rendered result of that utility plus a hover variant that widens the bloom (hover:[text-shadow:...]).

The markup here is the compiled output so it previews without a build step; the annotation shows the source class string a Tailwind dev would actually write, mapping each layer to a theme() colour token.

Make it yours

  • Register once in tailwind.config under addUtilities as .text-neon so you write one class, not a long arbitrary value.
  • Drive the hue from a theme(colors.*) token so it stays on your palette.
  • Add text-neon-sm / text-neon-lg variants for a glow scale.
  • Pair with hover: and motion-safe:animate-pulse for interactive/animated neon in-utility.

Gotchas — read before shipping

  • Arbitrary values need underscores for spaces inside the bracket (0_0_10px) — a real space breaks the class.
  • Don't inline the giant arbitrary value on every element; register a named utility so the intent (and the palette) stays DRY.
  • Purge/JIT must see the full class string — dynamically concatenated class names get tree-shaken away.

Floor set by oklch(), color-mix() as this demo is written. The core technique itself goes back further — Chrome 80+.

Rendered output is plain text-shadow (universal). Tailwind arbitrary values require Tailwind 3.0+ / JIT.
