What this skill does

# 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

```css
: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

```css
/* 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](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

```css
/* 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

```css
@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)

```bash
# 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)

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

# 2. Develop
npm run dev

# 3. Deploy to Vercel
vercel
```

## Project Structure

## Site Config Pattern

Keep all editable content in one file:

```typescript
// 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: "..." },
  ],
  
  footer: {
    links: [...],
    social: [...],
  }
}
```
