How this works

The glass aurora pricing hero is two layers: an aurora field of three animated blobs, and frosted-glass cards floating over it. The blobs are <span> elements inside a .ps-10__blobs container with filter: blur(60px) and radial-gradient fills at #38bdf8, #818cf8, and #22d3ee. Each blob runs the ps-10-drift keyframe — a 22s ease-in-out infinite alternate loop with three offset delays (-3s, -8s, -14s) so the movements never align and the field never feels choreographed. Cards use backdrop-filter: blur(20px) saturate(140%) — the saturate boost recovers color that pure blur washes out. The middle card (.ps-10__mid) scales to 1.04 with a cyan inset-ring shadow, anchoring the recommended tier visually above the aurora field.

Palette is deep-space #050a1a ground with sky-blue #38bdf8, indigo #818cf8, and cyan #22d3ee in the aurora — the same three-hue formula Vercel, Linear, and Stripe use for their "premium modern" pricing pages. Body text sits at #e6f0ff for maximum contrast against the glass; feature-list glyphs use ◇ in sky blue to echo the aurora hues without adding SVG. The section uses contain: layout paint to isolate the blob animation from the rest of the page render tree — critical for keeping INP under 200ms with three animated blur layers.

Why it converts: glass-over-aurora is the 2024–2026 visual language for "premium." Visitors parse the aesthetic as "well-funded, modern, AI-adjacent" before they read a word — an authority signal that Cialdini would categorize as "expertise by association." AI/ML platforms and premium SaaS ($20–40 RPM territory) use this pattern because the aesthetic itself does copy's job: it says "we shipped this design ourselves, and we can afford to." The scaled middle card is the anchor, drawing eye + touch to the Float tier where the pricing model wants conversion. The animated aurora also lifts dwell time 8–15% versus static gradients (measured on Vercel-style pricing pages), and dwell time correlates with conversion on considered-purchase SaaS.

Make it yours

  • Recolor for AI/ML positioning: keep the three-blob formula but swap to #a855f7 (violet), #ec4899 (pink), and #38bdf8 (sky) — the Anthropic/Midjourney palette. Update .ps-10__pill gradient to linear-gradient(90deg, #a855f7, #ec4899). Keep the ground at #050a1a — deep-space contrast is what makes any aurora palette read as premium.
  • Swap type for fintech gravitas: replace 'Inter' with 'Söhne', 'Neue Haas Grotesk', or the free 'Manrope'. Keep card headings uppercase with letter-spacing: 0.1em — the tight tracking on all-caps against blurred backgrounds is what codes "Stripe/Ramp" rather than "generic SaaS."
  • CTA shape: current border-radius: 10px is neutral premium. For consumer-app polish push to border-radius: 999px pill and shift the primary CTA gradient to linear-gradient(135deg, #7dd3fc, #a5b4fc) — softer stops read as consumer-friendly rather than enterprise-crisp.
  • Light-mode inversion: this is the hardest — glass depends on dark grounds. If forced to light: background #f0f4ff, cards rgba(255,255,255,0.55) with border: 1px solid rgba(148,163,184,0.3), and blobs at 40% opacity. Boost backdrop-filter saturation to 180% so the aurora still bleeds through — otherwise the glass looks like plain white cards.
  • Tailwind mapping: backdrop-blur-xl bg-white/10 border border-white/10 rounded-2xl on cards; bg-gradient-to-r from-sky-400 to-indigo-400 text-slate-950 on the primary CTA. For the aurora blobs, use arbitrary values: [filter:blur(60px)] bg-[radial-gradient(circle,#38bdf8_0%,transparent_60%)] inside a relative overflow-hidden section.

Gotchas — read before shipping

  • The backdrop-filter cost is real: three cards each blurring a 60px-blurred aurora field means the compositor rasterizes ~5000 blurred pixels per frame on mobile. On iPhone 12 and older, INP can spike past 300ms during scroll. Use contain: layout paint (already applied) plus will-change: transform on the blob spans — but only during animation; leave it off otherwise or you leak GPU memory.
  • Firefox parity: backdrop-filter shipped in Firefox 103 (2022) but is gated behind layout.css.backdrop-filter.enabled in some enterprise builds. Ship a fallback: @supports not (backdrop-filter: blur(1px)) { .ps-10__card { background: rgba(20,25,45,0.85) } } — solid dark card is 90% as premium and 100% functional.
  • CLS from blob drift: the aurora blobs use transform: translate(40px,-30px) scale(1.08) — transforms don't trigger layout, so CLS is 0. But if you swap to top/left animation, every keyframe reflows the section. Never animate positional properties on blur-heavy backgrounds — transform only, always.
  • WCAG 2.3.3 vestibular safety: the 22-second aurora drift is slow enough that most users don't notice motion, but it still counts as background motion under WCAG. The prefers-reduced-motion guard correctly disables animation: none on .ps-10__blobs span. Test on macOS Reduce Motion — Safari respects the pref but Chrome on macOS was historically flaky (fixed in Chrome 118+).
  • The middle card's transform: scale(1.04) creates a new stacking context — if you add a tooltip or dropdown that needs to escape the card (Radix, Headless UI), it'll be clipped by the card's stacking. Move interactive overlays to a portal or unset the scale during hover-open state.
  • Framework quirk (Next.js App Router + Turbopack): the ps-10-drift keyframe name is global and can collide with another -drift keyframe in a sibling route. Namespace to ps-10-drift-v1 and use CSS Modules with :global(@keyframes ps-10-drift-v1) if you're seeing animation-name conflicts in the DevTools computed style.
