Frontend Design Ultimate

Create distinctive, production-grade static sites from text requirements alone. No mockups, no Figma — just describe what you want and get bold, memorable designs.

Stack: React 18 + TypeScript + Tailwind CSS + shadcn/ui + Framer Motion
Output: Vite (static HTML) or Next.js (Vercel-ready)

Quick Start

"Build a SaaS landing page for an AI writing tool. Dark theme, 
editorial typography, subtle grain texture. Pages: hero with 
animated demo, features grid, pricing table, FAQ accordion, footer."

Design Thinking (Do This First)

Before writing any code, commit to a BOLD aesthetic direction:

1. Understand Context

• Purpose: What problem does this interface solve? Who uses it?
• Audience: Developer tools? Consumer app? Enterprise? Creative agency?
• Constraints: Performance requirements, accessibility needs, brand guidelines?

2. Choose an Extreme Tone

Pick ONE and commit fully — timid designs fail:

| Tone | Characteristics | |------|-----------------| | Brutally Minimal | Sparse, monochrome, massive typography, raw edges | | Maximalist Chaos | Layered, dense, overlapping elements, controlled disorder | | Retro-Futuristic | Neon accents, geometric shapes, CRT aesthetics | | Organic/Natural | Soft curves, earth tones, hand-drawn elements | | Luxury/Refined | Subtle animations, premium typography, restrained palette | | Editorial/Magazine | Strong grid, dramatic headlines, whitespace as feature | | Brutalist/Raw | Exposed structure, harsh contrasts, anti-design | | Art Deco/Geometric | Gold accents, symmetry, ornate patterns | | Soft/Pastel | Rounded corners, gentle gradients, friendly | | Industrial/Utilitarian | Functional, monospace, data-dense |

3. Define the Unforgettable Element

What's the ONE thing someone will remember? A hero animation? Typography treatment? Color combination? Unusual layout?

Aesthetics Guidelines

Typography — NEVER Generic

BANNED: Inter, Roboto, Arial, system fonts, Open Sans

DO: Distinctive, characterful choices that elevate the design.

| Use Case | Approach | |----------|----------| | Display/Headlines | Bold personality — Clash, Cabinet Grotesk, Satoshi, Space Grotesk (sparingly), Playfair Display | | Body Text | Refined readability — Instrument Sans, General Sans, Plus Jakarta Sans | | Monospace/Code | DM Mono, JetBrains Mono, IBM Plex Mono | | Pairing Strategy | Contrast weights (thin display + bold body), contrast styles (serif + geometric sans) |

Size Progression: Use 3x+ jumps, not timid 1.5x increments.

Color & Theme

BANNED: Purple gradients on white, evenly-distributed 5-color palettes

DO:

• Dominant + Sharp Accent: 70-20-10 rule (primary-secondary-accent)
• CSS Variables: --primary, --accent, --surface, --text
• Commit to dark OR light: Don't hedge with gray middle-grounds
• High contrast CTAs: Buttons should pop dramatically

:root {
  --bg-primary: #0a0a0a;
  --bg-secondary: #141414;
  --text-primary: #fafafa;
  --text-secondary: #a1a1a1;
  --accent: #ff6b35;
  --accent-hover: #ff8555;
}

Motion & Animation

Priority: One orchestrated page load > scattered micro-interactions

High-Impact Moments:

• Staggered hero reveals (animation-delay)
• Scroll-triggered section entrances
• Hover states that surprise (scale, color shift, shadow depth)
• Smooth page transitions

Implementation:

• CSS-only for simple animations
• Framer Motion for React (pre-installed via init scripts)
• Keep durations 200-400ms (snappy, not sluggish)

Spatial Composition

BANNED: Centered, symmetrical, predictable layouts

DO:

• Asymmetry with purpose
• Overlapping elements
• Diagonal flow / grid-breaking
• Generous negative space OR controlled density (pick one)
• Off-grid hero sections

Backgrounds & Atmosphere

BANNED: Solid white/gray backgrounds

DO:

• Gradient meshes (subtle, not garish)
• Noise/grain textures (SVG filter or CSS)
• Geometric patterns (dots, lines, shapes)
• Layered transparencies
• Dramatic shadows for depth
• Blur effects for glassmorphism

/* Subtle grain overlay */
.grain::before {
  content: '';
  position: fixed;
  inset: 0;
  background: url("data:image/svg+xml,...") repeat;
  opacity: 0.03;
  pointer-events: none;
}

Mobile-First Patterns

See references/mobile-patterns.md for detailed CSS.

Critical Rules

| Pattern | Desktop | Mobile Fix | |---------|---------|------------| | Hero with hidden visual | 2-column grid | Switch to display: flex (not grid) | | Large selection lists | Horizontal scroll | Accordion with category headers | | Multi-column forms | Side-by-side | Stack vertically | | Status/alert cards | Inline | align-items: center + text-align: center | | Feature grids | 3-4 columns | Single column |

Breakpoints

/* Tablet - stack sidebars */
@media (max-width: 1200px) { }

/* Mobile - full single column */
@media (max-width: 768px) { }

/* Small mobile - compact spacing */
@media (max-width: 480px) { }

Font Scaling

@media (max-width: 768px) {
  .hero-title { font-size: 32px; }      /* from ~48px */
  .section-title { font-size: 24px; }   /* from ~32px */
  .section-subtitle { font-size: 14px; } /* from ~16px */
}

Build Workflow

Option A: Vite (Pure Static)

# 1. Initialize
bash scripts/init-vite.sh my-site
cd my-site

# 2. Develop
npm run dev

# 3. Build static files
npm run build
# Output: dist/

# 4. Bundle to single HTML (optional)
bash scripts/bundle-artifact.sh
# Output: bundle.html

Option B: Next.js (Vercel Deploy)

# 1. Initialize
bash scripts/init-nextjs.sh my-site
cd my-site

# 2. Develop
npm run dev

# 3. Deploy to Vercel
vercel

Site Config Pattern

Keep all editable content in one file:

// config/site.ts
export const siteConfig = {
  name: "Acme AI",
  tagline: "Write better, faster",
  description: "AI-powered writing assistant",
  
  hero: {
    badge: "Now in beta",
    title: "Your words,\nsupercharged",
    subtitle: "Write 10x faster with AI that understands your style",
    cta: { text: "Get Started", href: "/signup" },
    secondaryCta: { text: "Watch Demo", href: "#demo" },
  },
  
  features: [
    { icon: "Zap", title: "Lightning Fast", description: "..." },
    // ...
  ],
  
  pricing: [
    { name: "Free", price: 0, features: [...] },
    { name: "Pro", price: 19, features: [...], popular: true },

  faq: [
    { q: "How does it work?", a: "..." },
