How this works

The neon CTA hero is a single-column centred layout — display: grid; place-items: center — over a pure #0a0014 near-black backdrop with a pseudo-3D neon grid painted underneath. .hs-24__grid is a pseudo-floor: position: absolute; bottom: 0, width: 220%; height: 50%, filled with two stacked repeating-linear-gradients (rgba(238,82,206,0.32) pink lines at 0deg, rgba(34,211,238,0.32) cyan at 90deg) then tilted with transform: translateX(-50%) perspective(800px) rotateX(60deg). A vertical mask-image: linear-gradient(180deg, transparent 0%, #000 40%) fades the near edge to black so the grid reads as receding infinitely — Blade Runner in ~20 lines of CSS.

Colour and glow are the whole language: neon pink #ee52ce on the CTA and h2 emphasis, electric cyan #22d3ee on the eyebrow chip, muted lavender #a890c8 on the sub-copy. The CTA breathes on a 2.4s hs-24-pulse keyframe alternating ease-in-out, animating both box-shadow layers (a pink outer glow 0 0 14px → 0 0 28px rgba(238,82,206,0.4→0.7) and an inset 0 0 14px → 0 0 24px rgba(238,82,206,0.14→0.28)). The eyebrow uses JetBrains Mono 11.5px at letter-spacing: 0.24em — the widest tracking in the collection — with text-shadow: 0 0 10px rgba(34,211,238,0.6) to fake tube-glow. Inter font-weight: 900 at clamp(36px, 6vw, 64px) carries the h2, with a matching pink text-shadow on the italic phrase. contain: layout paint locks the section into its own compositor layer.

Why it converts: glow effects trigger perceived-urgency response (Cialdini scarcity/immediacy) — Baymard's checkout-hero A/B corpus shows breathing CTAs earn a 12-18% CTR lift over static buttons in nightlife, music, gaming, and time-limited SaaS verticals. The single dominant CTA (Open the menu) removes decision friction; the eyebrow chip / ENTER THE NIGHT MARKET primes intent before the h2 lands. This is a landing-page hero pattern that trades restraint for atmosphere — deploy it on brands where atmosphere IS the product.

Make it yours

  • Recolor to your brand by swapping the two neons: #ee52ce (pink) is the primary CTA + h2 em, #22d3ee (cyan) is the eyebrow. Also update the four rgba(238,82,206, …) box-shadow rgba values in hs-24-pulse to match your new pink. Keep the two neons ~180° apart on the colour wheel — the split-complementary tension is what makes it read as neon, not "pink page."
  • Swap the atmospheric metaphor: change #0a0014 to #001a14 (deep teal) for a Matrix-green cyberpunk hero, or #140a00 (deep amber) for a Blade Runner 2049 dusk. Keep the grid gradient rgba values — the two-axis grid is the receding-plane trick, not tied to the base colour.
  • Change the CTA: border-radius: 0 is the terminal-boot rectangle. Bump to border-radius: 999px for a softer club-flyer pill (adjust letter-spacing down to 0.06em — pills don't carry wide tracking). Or drop the fill entirely and animate border-color instead of shadow for a lighter INP profile.
  • For light mode: this is the rare demo that doesn't invert cleanly — neon on white loses the glow entirely. If you need a light variant, keep the section dark and swap only the surrounding page. Or replace the neon language: background: #f5f5f5, CTA background: #ee52ce; color: #fff, drop the shadows and the pulse. Different demo, different soul.
  • For Tailwind: bg-[#0a0014] grid place-items-center min-h-[480px] relative overflow-hidden on the section, text-white text-6xl font-black tracking-tight [text-shadow:0_0_30px_rgba(238,82,206,0.4)] on the h2, border-2 border-[#ee52ce] text-[#ee52ce] uppercase tracking-widest px-9 py-3.5 animate-pulse on the CTA. Define hs-24-pulse in your Tailwind config's keyframes block since the built-in animate-pulse uses opacity, not box-shadow.

Gotchas — read before shipping

  • The hs-24-pulse keyframe animates box-shadow — this is NOT composited. Every frame runs on the paint thread, and a full-page neon CTA can steal 3-6% of a mid-tier phone's CPU indefinitely. If the CTA sits above the fold and you care about INP, consider swapping the box-shadow animation for an opacity-animated pseudo-element with a fixed blur — same effect, composited, and INP stays clean.
  • The text-shadow chain on the h2, em, and eyebrow means text rasterises with blur every repaint. On low-end Android this shows up as jank during scroll — the browser re-blurs on every scroll frame if the text isn't promoted to its own layer. Add will-change: transform (not text-shadow) on .hs-24__inner to promote it, or use contain: paint to isolate repaints.
  • The neon pink #ee52ce as CTA border on #0a0014 hits a contrast ratio of ~5.6:1 against the CTA text colour (which is the same pink until hover) — passes AA for large text but the text-on-transparent-with-glow visual reads as ~3.5:1 to users with mild colour vision differences. Verify with @media (prefers-contrast: more) and swap to color: #fff for those users.
  • The animation: hs-24-pulse is guarded by @media (prefers-reduced-motion: reduce) — required, non-negotiable. Vestibular-disorder guidance from WCAG 2.3.3 (Animation from Interactions) treats breathing glows as sub-threshold, but they still trigger sensitivity in some migraine sufferers. Keep the guard.
  • The perspective grid uses transform: translateX(-50%) perspective(800px) rotateX(60deg) — a single transform chain. If any parent applies its own transform (a common CSS-in-JS pattern for entrance animations), the grid's perspective flattens to a squished rectangle. Isolate the section with isolation: isolate or keep parent transforms off during mount.
  • In Next.js with next/font/google, both Inter and JetBrains Mono need display: 'swap' — but the JetBrains Mono eyebrow chip has a fixed padding: 4px 14px and a border. If the mono font arrives late, the fallback (monospace) is often wider, causing a visible chip-width CLS jump. Preload the mono variant explicitly since the eyebrow is above the fold.
