Frontend Design Skill

Use this skill when creating UI components, landing pages, dashboards, or any frontend design work.

Design Workflow

Follow this structured approach for UI design:

Layout Design — Think through component structure, create ASCII wireframes
Theme Design — Define colors, fonts, spacing, shadows
Animation Design — Plan micro-interactions and transitions
Implementation — Generate the actual code

1. Layout Design

Before coding, sketch the layout in ASCII format:

┌─────────────────────────────────────┐
│         HEADER / NAV BAR            │
├─────────────────────────────────────┤
│                                     │
│            HERO SECTION             │
│         (Title + CTA)               │
│                                     │
├─────────────────────────────────────┤
│   FEATURE   │  FEATURE  │  FEATURE  │
│     CARD    │   CARD    │   CARD    │
├─────────────────────────────────────┤
│            FOOTER                   │
└─────────────────────────────────────┘

2. Theme Guidelines

Color Rules:

NEVER use generic bootstrap-style blue (#007bff) — it looks dated
Prefer oklch() for modern color definitions
Use semantic color variables (--primary, --secondary, --muted, etc.)
Consider both light and dark mode from the start

Font Selection (Google Fonts):

Sans-serif: Inter, Roboto, Poppins, Montserrat, Outfit, Plus Jakarta Sans, DM Sans, Space Grotesk
Monospace: JetBrains Mono, Fira Code, Source Code Pro, IBM Plex Mono, Space Mono, Geist Mono
Serif: Merriweather, Playfair Display, Lora, Source Serif Pro, Libre Baskerville
Display: Architects Daughter, Oxanium

Spacing & Shadows:

Use consistent spacing scale (0.25rem base)
Shadows should be subtle — avoid heavy drop shadows
Consider using oklch() for shadow colors too

3. Theme Patterns

Modern Dark Mode (Vercel/Linear style):

:root {
  --background: oklch(1 0 0);
  --foreground: oklch(0.145 0 0);
  --primary: oklch(0.205 0 0);
  --primary-foreground: oklch(0.985 0 0);
  --secondary: oklch(0.970 0 0);
  --muted: oklch(0.970 0 0);
  --muted-foreground: oklch(0.556 0 0);
  --border: oklch(0.922 0 0);
  --radius: 0.625rem;
  --font-sans: Inter, system-ui, sans-serif;
}

Neo-Brutalism (90s web revival):

:root {
  --background: oklch(1 0 0);
  --foreground: oklch(0 0 0);
  --primary: oklch(0.649 0.237 26.97);
  --secondary: oklch(0.968 0.211 109.77);
  --accent: oklch(0.564 0.241 260.82);
  --border: oklch(0 0 0);
  --radius: 0px;
  --shadow: 4px 4px 0px 0px hsl(0 0% 0%);
  --font-sans: DM Sans, sans-serif;
  --font-mono: Space Mono, monospace;
}

Glassmorphism:

.glass {
  background: rgba(255, 255, 255, 0.1);
  backdrop-filter: blur(10px);
  border: 1px solid rgba(255, 255, 255, 0.2);
  border-radius: 1rem;
}

4. Animation Guidelines

Micro-syntax for planning:

button: 150ms [S1→0.95→1] press
hover: 200ms [Y0→-2, shadow↗]
fadeIn: 400ms ease-out [Y+20→0, α0→1]
slideIn: 350ms ease-out [X-100→0, α0→1]
bounce: 600ms [S0.95→1.05→1]

Common patterns:

Entry animations: 300-500ms, ease-out
Hover states: 150-200ms
Button press: 100-150ms
Page transitions: 300-400ms

5. Implementation Rules

Tailwind CSS:

<!-- Import via CDN for prototypes -->
<script src="https://cdn.tailwindcss.com"></script>

Flowbite (component library):

<link href="https://cdn.jsdelivr.net/npm/flowbite@2.0.0/dist/flowbite.min.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/flowbite@2.0.0/dist/flowbite.min.js"></script>

Icons (Lucide):

<script src="https://unpkg.com/lucide@latest/dist/umd/lucide.min.js"></script>
<script>lucide.createIcons();</script>

Images:

Use real placeholder services: Unsplash, placehold.co
Never make up image URLs
Example: https://images.unsplash.com/photo-xxx?w=800&h=600

6. Responsive Design

Always design mobile-first and responsive:

/* Mobile first */
.container { padding: 1rem; }

/* Tablet */
@media (min-width: 768px) {
  .container { padding: 2rem; }
}

/* Desktop */
@media (min-width: 1024px) {
  .container { max-width: 1200px; margin: 0 auto; }
}

7. Accessibility

Use semantic HTML (header, main, nav, section, article)
Include proper heading hierarchy (h1 → h2 → h3)
Add aria-labels to interactive elements
Ensure sufficient color contrast (4.5:1 minimum)
Support keyboard navigation

8. Component Design Tips

Cards:

Subtle shadows, not heavy drop shadows
Consistent padding (p-4 to p-6)
Hover state: slight lift + shadow increase

Buttons:

Clear visual hierarchy (primary, secondary, ghost)
Adequate touch targets (min 44x44px)
Loading and disabled states

Forms:

Clear labels above inputs
Visible focus states
Inline validation feedback
Adequate spacing between fields

Navigation:

Sticky header for long pages
Clear active state indication
Mobile-friendly hamburger menu

Quick Reference

Element	Recommendation
Primary font	Inter, Outfit, DM Sans
Code font	JetBrains Mono, Fira Code
Border radius	0.5rem - 1rem (modern), 0 (brutalist)
Shadow	Subtle, 1-2 layers max
Spacing	4px base unit (0.25rem)
Animation	150-400ms, ease-out
Colors	oklch() for modern, avoid generic blue
