Wednesday Design & UX Guidelines

Trigger

Load this skill when working on UI, components, or visual design:

• Building or modifying a React component
• Choosing which UI component to use
• Styling with Tailwind or design tokens
• Adding animations or transitions
• Accessibility review of a UI element
• "Which component should I use for X?"
• "How should this look?"

Do NOT use this skill for: business logic, TypeScript types, API routes, or code structure (use wednesday-dev). This skill only applies to visual output and UI components.

⚠️ CRITICAL: APPROVED COMPONENT LIBRARY ONLY

THIS IS A MANDATORY REQUIREMENT. NO EXCEPTIONS.

The Rule

DO NOT create custom UI components. All UI elements MUST be sourced from the approved component library containing 492+ pre-vetted components from 8 libraries.

Why This Matters

1. Consistency - Pre-built components ensure visual coherence across all projects
2. Quality - These components are battle-tested, accessible, and performant
3. Speed - No time wasted reinventing existing solutions
4. Maintenance - Upstream updates benefit all projects

Approved Libraries (Priority Order)

Before Writing ANY Component

┌─────────────────────────────────────────────────────────────┐
│  STOP! Ask yourself:                                        │
│                                                             │
│  1. Does this component exist in the approved library?      │
│     └─> YES: Use it. STOP here.                             │
│     └─> NO: Continue to step 2                              │
│                                                             │
│  2. Can I combine 2-3 approved components to achieve this?  │
│     └─> YES: Compose them. STOP here.                       │
│     └─> NO: Continue to step 3                              │
│                                                             │
│  3. Can I extend an approved component's styles only?       │
│     └─> YES: Extend styles using design tokens. STOP here.  │
│     └─> NO: Escalate to tech lead for approval              │
│                                                             │
│  ❌ NEVER create a component from scratch                   │

Violation Examples

// ❌ WRONG - Creating custom button
function CustomButton({ children }) {
  return <button className="bg-green-500 ...">{children}</button>
}

// ✅ CORRECT - Using approved library
import { ShimmerButton } from '@/components/magicui/shimmer-button'
// or
import { Button } from '@/components/ui/button'

// ❌ WRONG - Creating custom card animation
function AnimatedCard({ children }) {
  return <motion.div whileHover={{ scale: 1.05 }}>{children}</motion.div>
}

// ✅ CORRECT - Using approved library
import { WobbleCard } from '@/components/aceternity/wobble-card'
// or
import { MagicCard } from '@/components/magicui/magic-card'

// ❌ WRONG - Creating custom text animation
function TypewriterText({ text }) {
  // custom implementation...
}

// ✅ CORRECT - Using approved library
import { TypewriterEffect } from '@/components/aceternity/typewriter-effect'
// or
import { TypingAnimation } from '@/components/magicui/typing-animation'

Quick Lookup by Need

See references/COMPONENT-LIBRARY.md for the complete index of 492+ approved components.

1. Visual Design Principles

Brand Identity

• Primary palette: Green (#4ADE80) to Teal (#0D9488) gradient
• Typography: Instrument Serif for display, DM Sans for body
• Aesthetic: Premium, minimal, with subtle depth and glow effects

Design Hierarchy

1. Primary actions - Green gradient with glow
2. Secondary actions - Outlined, neutral
3. Content - Cards with subtle elevation
4. Background - Dot patterns, spotlights, gradients

Spacing System

Use a 4px base grid:

• Small gaps: 8px, 12px
• Medium gaps: 16px, 24px
• Large gaps: 32px, 48px
• Section spacing: 56px

See references/TOKENS.md for complete token definitions.

2. Typography Guidelines

Hierarchy

Display XL: 60px - Hero headlines
Display LG: 44px - Section headlines
Display MD: 38px - Feature headlines
Display SM: 28px - Card headlines

Body LG: 18px - Lead paragraphs
Body MD: 16px - Standard body text
Body SM: 14px - Supporting text
Body XS: 12px - Captions, labels

Font Pairing

// Display/Headlines - elegant, editorial feel
fontFamily: "'Instrument Serif', Georgia, serif"

// Body/UI - clean, readable
fontFamily: "'DM Sans', -apple-system, sans-serif"

Text Styling Rules

1. Headlines use Instrument Serif, normal weight, negative letter-spacing
2. Body uses DM Sans, regular to semibold weights
3. Labels/Overlines are uppercase with expanded letter-spacing (0.1em+)
4. Emphasized text in headlines uses italic style
5. Muted text uses #71717A color

3. Color Usage

Semantic Colors

Gradient Usage

• Brand gradient: linear-gradient(135deg, #4ADE80 0%, #0D9488 100%)
• Use for primary CTAs, badges, icons
• Never use flat colors for primary actions

Dark Cards

For AI/system messages or contrast:

• Background: linear-gradient(135deg, #18181B 0%, #27272A 100%)
• Text: White (#FFFFFF) with muted gray (#A3A3A3) for descriptions

4. Animation Principles

Core Rules

1. Purpose-driven - Every animation serves a purpose (feedback, hierarchy, delight)
2. Performance-first - Only animate transform and opacity
3. Consistent timing - Use standardized easings and durations
4. Respect preferences - Honor prefers-reduced-motion

Timing Guidelines

Scroll-Driven Animations

For landing pages and storytelling:

1. Use scroll progress (0-1) to drive animations
2. Define clear phase thresholds for content reveals
3. Stagger elements within each phase
4. Provide fallbacks for reduced motion

See references/ANIMATIONS.md for implementation patterns.

5. Component Standards

Cards

• Border radius: 24px for cards, 14px for buttons
• Padding: 22px standard, 28px for prominent cards
• Shadows: Layered shadows with optional glow
• Hover: Lift effect (-8px) with enhanced shadow

Buttons

Primary buttons should have:

• 3D gradient background (not flat)
• Top highlight line
• Shimmer animation
• Press/hover states with transform feedback
• Arrow icon that animates on hover

Badges

Premium badges include:

• Subtle gradient background
• Pulse dot for "live" states
• Shimmer effect
• Rounded pill shape (100px radius)

See references/COMPONENTS.md for code patterns.

6. Interaction Design

Hover States

Press States

• Scale down slightly (0.98)
• Reduce shadow depth
• Darken background
• Remove shimmer/highlight effects

Focus States

• Visible focus ring (0 0 0 2px primary-color)
• Never remove outline without alternative
• High contrast for keyboard navigation

8. Accessibility Requirements

Color Contrast

• Text on backgrounds: Minimum 4.5:1 ratio
• Large text (24px+): Minimum 3:1 ratio
• UI components: Minimum 3:1 ratio

Motion Accessibility

@media (prefers-reduced-motion: reduce) {
  *,
  *::before,
  *::after {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;
  }
}

Keyboard Navigation

• All interactive elements must be focusable
• Tab order follows visual order
• Focus indicators are always visible
• Escape closes modals/dropdowns

Screen Readers

• Images have descriptive alt text
• Icons have aria-labels
• Dynamic content uses aria-live regions
• Form fields have associated labels

9. Responsive Design

Breakpoints

const breakpoints = {
  sm: '640px',   // Mobile landscape
  md: '768px',   // Tablet
  lg: '1024px',  // Desktop
  xl: '1280px',  // Large desktop
  '2xl': '1536px', // Extra large
}

Mobile Considerations

• Touch targets minimum 44x44px
• Increased font sizes for readability
• Simplified animations
• Stack layouts vertically
• Hide decorative elements

10. Performance Guidelines

Image Optimization

• Use next/image for automatic optimization
• Provide width/height to prevent layout shift
• Use WebP format with JPEG fallback
• Lazy load below-the-fold images

Animation Performance

• Only animate transform and opacity
• Use will-change sparingly during active animations
• Debounce scroll handlers
• Use requestAnimationFrame for JS animations

CSS Best Practices

• Minimize use of filter and backdrop-filter
• Avoid animating box-shadow (use opacity on pseudo-element)
• Use CSS containment where appropriate

Quick Reference

Do's

• Use gradients for primary actions
• Add subtle glow effects to featured elements
• Include hover/press state feedback
• Use staggered animations for lists
• Test with keyboard navigation
• Provide loading/skeleton states

Don'ts

• Create custom components - Use approved library ONLY
• Reinvent existing solutions - Check library first
• Use flat colors for CTAs
• Skip hover states on interactive elements
• Animate layout properties (width, height, margin)
• Ignore reduced motion preferences
• Create text with insufficient contrast
• Use autoplay video without controls

Reference Documents
