## Overview

Vibrant gradient interface inspired by Northern Lights with mesh gradients, smooth color blends, flowing animations. Ideal for saas premium, creative tools, agência moderna, brand exclusiva. AI-ready template. Stripe changed everything. Around 2020, their landing page dropped those animated mesh gradients and suddenly every SaaS founder wanted "that Stripe look." But the technique itself goes deeper — mesh gradients existed in Illustrator for decades, largely ignored by web designers because CSS couldn't reproduce them. Then Figma shipped native mesh gradient plugins, Josh Comeau wrote about CSS gradient animations, and the floodgates opened.

The aurora aesthetic — those slow-moving, Northern Lights color fields — emerged as designers realized static gradients felt dated. Movement was the differentiator. CSS Houdini's @property rule finally let us animate color stops without JavaScript hacks, and suddenly you could get buttery 60fps gradient transitions with pure CSS. The performance story matters here: animated gradients done wrong will torch mobile batteries and trigger compositing nightmares.

By 2023, the trend matured. The best implementations use subtle, slow movement — think 8-12 second animation cycles — rather than the frantic color-shifting that plagued early attempts. Restraint won.

## Layout

- **Grid:** CSS Grid primary. Max-width containment: 1280px centered with 1.5rem side padding.
- **Spacing rhythm:** Balanced. Base unit: 0.5rem (8px).
- **Section vertical gaps:** clamp(4rem, 8vw, 8rem).
- **Hero layout:** Split-screen (text left, visual right).
- **Feature sections:** Zig-zag alternating text+image rows. No 3-equal-columns.
- **Mobile collapse:** All multi-column layouts collapse below 768px. No horizontal overflow.
- **z-index contract:** base (0) / sticky-nav (100) / overlay (200) / modal (300) / toast (500).


## Elevation & Depth

Large flowing CSS/SVG gradients, subtle 8-12s animations, depth via color layering, smooth morph

- **Physics:** Spring — stiffness 120, damping 20. Confident, weighted transitions.
- **Entry animations:** Fade + translate-Y (16px → 0) over 480ms ease-out. Staggered cascades for lists: 100ms between items.
- **Hover states:** Scale(1.03) + shadow lift over 200ms.
- **Page transitions:** Fade + slide (300ms).
- **Performance:** Only transform and opacity animated. No layout-triggering properties.




## Shapes

Base corner radius: 4px. See rounded tokens in front matter for the full scale.

## Components

- **Primary Button:** Moderately rounded (0.75rem) shape. Accent color fill. Hover: 8% darken + subtle lift shadow. Active: -1px translate tactile press. Font weight 600. No outer glows.
- **Secondary / Ghost Button:** Outline variant. 1.5px border in muted color. Text in primary color. Hover: subtle background fill.
- **Cards:** Moderately rounded (0.75rem) corners. Surface background. Subtle shadow (0 2px 12px rgba(0,0,0,0.06)). 1px border stroke.
- **Inputs:** Label above input. 1px border stroke. Focus ring: 2px accent color offset 2px. Error text below in semantic red. No floating labels.
- **Navigation:** Primary surface background. Active item: accent color indicator. Font weight 500 when active.
- **Skeletons:** Shimmer animation matching component dimensions. No circular spinners.
- **Empty States:** Icon-based composition with descriptive text and action button.


## Do's and Don'ts

- No emojis in UI — use icon system only (Lucide, Heroicons)
- No pure black (#000000) — use off-black or charcoal variants
- No oversaturated accent colors (saturation cap: 80%)
- No 3-column equal-width feature layouts — use zig-zag or asymmetric grid
- No `h-screen` — use `min-h-[100dvh]`
- No AI copywriting clichés: "Elevate", "Seamless", "Unleash", "Next-Gen"
- No broken external image links — use picsum.photos or inline SVG
- No generic lorem ipsum in demos

- Do Mesh/flowing gradients applied
- Do 8-12s animation loop
- Do Complementary colors used
- Do Smooth color transitions
- Do Iridescent effect subtle
- Do Text contrast verified


## Use Case

SaaS premium, Creative tools, Agência moderna, Brand exclusiva

Act as a Senior Frontend Engineer and Expert UI Designer.
Your task is to code a complete Landing Page on the first attempt.
- Landing Page Theme: <INSERT THEME>
- Sections to add: <INSERT SECTIONS>

Generate the final code immediately following these definitions:

## Style

- **Name:** Aurora UI
- **Type:** Ethereal, Gradient, Premium, Animated
- **Keywords:** Vibrant gradients, smooth blend, Northern Lights effect, mesh gradient, luminous, atmospheric, abstract
- **Era:** 2020s Modern
- **Light/Dark:** ✓ Full / ✓ Full

## Color Palette

- **Primary:** Complementary: Blue-Orange, Purple-Yellow, Electric Blue #0080FF, Magenta #FF1493, Cyan #00FFFF
- **Secondary:** Smooth transitions (Blue→Purple→Pink→Teal), iridescent effects, blend modes (screen, multiply)

## Visual Effects

Large flowing CSS/SVG gradients, subtle 8-12s animations, depth via color layering, smooth morph

## AI Visual Direction

Create a vibrant gradient interface inspired by Northern Lights with mesh gradients, smooth color blends, flowing animations. Use complementary color pairs (blue-orange, purple-yellow), flowing background gradients, subtle continuous animations (8-12s loops), iridescent effects.

## CSS Technical

```css
background: conic-gradient or radial-gradient with multiple stops, animation: @keyframes gradient (8-12s), background-size: 200% 200%, filter: saturate(1.2), blend-mode: screen or multiply
```

## Design System Variables

```css
--gradient-colors: complementary pairs, --animation-duration: 8-12s, --blend-mode: screen, --color-saturation: 1.2, --effect: iridescent, --loop-smooth: true
```

## Implementation Checklist

- ☐ Mesh/flowing gradients applied
- ☐ 8-12s animation loop
- ☐ Complementary colors used
- ☐ Smooth color transitions
- ☐ Iridescent effect subtle
- ☐ Text contrast verified

## Execution Rules

1. Strictly follow the defined visual style.
2. Use high-quality inline SVG icons (Heroicons or Lucide style) — NEVER use emojis as icons.
3. Add `cursor-pointer` and smooth `hover` states (transition-all) on all interactive elements.
4. Required Page Structure:
   - Navbar (Logo + Links + CTA)
   - Hero Section (Impactful Headline + Subtitle + 2 buttons + 3D/Abstract visual element via CSS)
   - Features (3 cards with icons)
   - Testimonials (3 cards)
   - Pricing (3 tiers, highlight the middle one)
   - Final CTA
   - Full Footer with social links, privacy policy, terms of use, contact and SEO links.
5. All text content must be in English.
6. The visual must be CLEARLY distinct — do not create a "default Bootstrap" design. Force the use of the provided design system variables.
7. Use `<style>` tags in the head for custom classes (especially for complex backdrop-filter effects and animations) that Tailwind CDN doesn't cover.
8. Full Responsiveness: Layout must adapt perfectly to Mobile, Tablet and Desktop (vertical stack on mobile).
9. Include basic SEO, Viewport and Open Graph meta tags in `<head>`.
10. Footer must contain: Copyright 2026, Secondary navigation links and Social media icons.
11. Make the creative decisions needed to deliver the complete, functional result now.
