Frontend Design Skill

Purpose: Create production-grade, distinctive UI that stands out from generic AI-generated designs

Quick Start

When to Use

•Building web UI components, pages, or applications
•Creating dashboard interfaces, landing pages, or marketing sites
•Styling React components, HTML/CSS layouts, or design systems

Quick Reference

Category	Key Principle	Action
Fonts	Avoid defaults	Never use Inter as default
Colors	Avoid gradients	No purple-to-blue gradients
Layout	Embrace asymmetry	Break from rigid grids
Details	Add texture	Use noise, patterns, borders

Core Principles

1. Choose an Aesthetic Direction

Direction	Characteristics	Examples
Minimalist	Clean, sparse, purposeful	Stripe, Linear
Maximalist	Bold, expressive, layered	Brutalist sites
Warm/Human	Organic textures, soft edges	Notion, Gumroad
Technical/Precise	Sharp edges, monospace	Vercel, GitHub
Playful	Bright colors, rounded	Discord, Slack

Action: Start with "I'll use a [direction] aesthetic for this."

2. Make Every Detail Intentional

•Default fonts → Never accept Inter as the default
•Gradients → Purple-to-blue is the most overused gradient
•Center alignment → Explore asymmetry and interesting layouts
•Flat colors → Add texture, noise, patterns, or subtle borders

3. Be Specific, Not Generic

Bad: "Use a nice color scheme" | Good: "Use a warm palette with coral (#FF6B6B) as primary, cream (#FFF8F0) background"

Typography & Color

Font Selection

⚠️ NEVER use Inter as the default font

Category	Font Families	When to Use
Serif	GT Super, Charter, Georgia	Editorial, premium
Sans-Serif	Geist, Satoshi, System UI	Clean, modern (not Inter!)
Monospace	Geist Mono, JetBrains Mono	Technical, code
Display	Clash Display, Syne	Headlines, personality

Typography Hierarchy: Headlines: 40-72px, tight tracking (-1% to -3%) | Body: 16-18px, loose tracking (0% to +2%)

Color Strategy

⚠️ Anti-Pattern: background: linear-gradient(135deg, #667eea 0%, #764ba2 100%); (purple-to-blue is everywhere)

Moods: Warm (coral, peach, cream) | Cool (teal, sage, slate) | Bold (red, yellow, black) | Muted (olive, rust, navy)

Palette example:

css

:root {
  --primary: #FF6B6B;      /* Coral */
  --background: #FFF8F0;   /* Cream */
  --text: #2D3436;
  --border: #E8E8E8;
}

Usage rules:

•Backgrounds: Off-white, cream, or dark (never pure #FFF)
•Borders: Subtle (opacity 0.1-0.2) or sharp black/white
•Gradients: Subtle, same-hue shifts (no purple-to-blue!)

Motion & Layout

Animation Principles

•Duration: 200-300ms for micro-interactions
•Easing: ease-out for entry, ease-in for exit
•Spring physics: cubic-bezier(0.34, 1.56, 0.64, 1)
•Examples: Hover: Scale up (1.02) | Click: Scale down (0.98) | Entry: Fade in + slide up (20px)

⚠️ Anti-Pattern: Over-Animation

Avoid: Spinning loaders, bounce effects, slow fade-ins (>500ms)

Layout Strategy

•Explore asymmetric layouts
•Use grid systems creatively
•Generous padding = premium feel

Component Spacing: Section (80-120px) | Component (24-32px) | Element (8-16px)

Anti-Patterns: The "AI Slop" Checklist

• Inter font default → Change
• Purple-to-blue gradient → Different scheme
• Perfectly centered → Explore asymmetry
• Pure white (#FFF) → Add texture
• Generic shadows → Use subtle
• No borders → Add separation
• Rounded-xl everywhere → Vary radius
• No texture/noise → Add interest

Implementation Tips

Tailwind CSS

jsx

/* Good: Specific values */
className="text-[17px] leading-[1.6] text-[#2D3436]"

/* Bad: Generic defaults */
className="text-base leading-normal text-gray-900"

React Components

jsx

const theme = { colors: { primary: '#FF6B6B' } };
<button style={{ backgroundColor: theme.colors.primary }} />
