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:

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.

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

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: "..." },

}

Pre-Implementation Checklist

Run this before finalizing any design:

Design Quality

• Typography is distinctive (no Inter/Roboto/Arial)
• Color palette has clear dominant + accent (not evenly distributed)
• Background has atmosphere (not solid white/gray)
• At least one memorable/unforgettable element
• Animations are orchestrated (not scattered)

Mobile Responsiveness

• Hero centers on mobile (no empty grid space)
• All grids collapse to single column
• Forms stack vertically
• Large lists use accordion (not horizontal scroll)
• Font sizes scale down appropriately

Form Consistency

• Input, select, textarea all styled consistently
• Radio/checkbox visible (check transparent-border styles)
• Dropdown options have readable backgrounds
• Labels use CSS variables (not hardcoded colors)

Accessibility

• Color contrast meets WCAG AA (4.5:1 text, 3:1 UI)
• Focus states visible
• Semantic HTML (nav, main, section, article)
• Alt text for images
• Keyboard navigation works

shadcn/ui Components

10 common components pre-installed (button, badge, card, accordion, dialog, navigation-menu, tabs, sheet, separator, avatar, alert). Add more with npx shadcn@latest add [name] or install all with npx shadcn@latest add --all.

See references/shadcn-components.md for full component reference.

Most used for landing pages:

• Button, Badge — CTAs and labels
• Card — Feature cards, pricing tiers
• Accordion — FAQ sections
• Dialog — Modals, video players
• NavigationMenu — Header nav
• Tabs — Feature showcases
• Carousel — Testimonials

Examples

Prompt → Output

Input:

"Portfolio site for a photographer. Minimal, editorial feel. Grid gallery with lightbox, about section, contact form."

Design Decisions:

• Tone: Editorial/Magazine
• Typography: Cormorant Garamond (display) + Inter... wait, banned. Plus Jakarta Sans (body)
• Color: Near-black bg (#0c0c0c), warm white text (#f5f5f0), copper accent (#b87333)
• Unforgettable: Full-bleed hero image with text overlay that reveals on scroll
• Motion: Gallery images fade in staggered on scroll

Output: Complete Next.js project with responsive gallery, lightbox component, and contact form with validation.
