dvcrn UI/UX Master Skill
The ultimate design skill combining Apple Human Interface Guidelines, modern web design patterns, SuperDesign principles, and universal UX best practices for creating exceptional user experiences across all platforms.
Design Philosophy
Core Principles
1. Clarity Over Cleverness
- Information hierarchy is obvious
- Actions are predictable
- Feedback is immediate
- Complexity is hidden when not needed
2. Consistency Breeds Familiarity
- Patterns repeat across the interface
- Terminology is uniform
- Visual language is coherent
- Platform conventions are respected
3. Beauty Through Simplicity
- Every element serves a purpose
- White space creates breathing room
- Visual noise is minimized
- Details are refined
4. Accessibility is Non-Negotiable
- Works for everyone, regardless of ability
- Keyboard navigable
- Screen reader friendly
- High contrast options available
Platform-Specific Design
Apple Platforms (iOS, macOS, watchOS, tvOS, visionOS)
For complete Apple HIG patterns, see references/apple-platforms.md
Key Apple Principles:
- Clarity: Legible text, precise icons, subtle adornments
- Deference: Content-first, UI stays out of the way
- Depth: Visual layers, realistic motion, spatial awareness
When to use: Native iOS, macOS, watchOS, tvOS, or visionOS apps
Modern Web Design
For complete web design patterns, see references/web-design.md
Key Web Principles:
- Responsive: Mobile-first, adapts to all screens
- Performant: Fast load times, optimized assets
- Progressive: Works everywhere, enhanced where possible
- Semantic: Proper HTML structure, accessible markup
When to use: Websites, web apps, PWAs, landing pages, dashboards
Design Systems
Color Theory
Modern Color Systems:
- oklch() color space (perceptually uniform, modern)
- HSL for quick adjustments
- RGB/Hex for legacy compatibility
Semantic Colors:
/* Light/Dark mode compatible */
--primary: oklch(0.649 0.237 267);
--secondary: oklch(0.556 0 0);
--background: oklch(0.145 0 0); /* dark */
--foreground: oklch(0.985 0 0); /* light text */
--muted: oklch(0.556 0 0 / 0.5);
--border: oklch(0.922 0 0 / 0.15);
Avoid:
- Generic bootstrap blue (#007bff) - dated
- Pure black (#000000) - use dark grays
- Low contrast text (<4.5:1 ratio)
Color Guidelines: See references/color-systems.md for palettes, contrast ratios, and color psychology
Typography
System Fonts (Recommended):
- Apple: SF Pro (iOS/macOS), SF Compact (watchOS)
- Web: Inter, Outfit, DM Sans, Plus Jakarta Sans
- Monospace: JetBrains Mono, Fira Code, Geist Mono
- Fallback: -apple-system, system-ui, sans-serif
Type Scale:
Display: 72px / 4.5rem
Heading 1: 48px / 3rem
Heading 2: 36px / 2.25rem
Heading 3: 24px / 1.5rem
Body: 16px / 1rem
Small: 14px / 0.875rem
Caption: 12px / 0.75rem
Line Height:
- Headings: 1.2 - 1.3
- Body: 1.5 - 1.6
- Small text: 1.4 - 1.5
Font Pairing: See references/typography.md for pairing rules and examples
Spacing & Layout
8-Point Grid System:
- Base unit: 8px (0.5rem)
- Spacing scale: 8, 16, 24, 32, 40, 48, 56, 64, 80, 96
- Use multiples of 4px for fine-tuning (4, 12, 20, 28, etc.)
Standard Margins:
- Mobile: 16px
- Tablet: 24px
- Desktop: 32-48px
- Max width: 1200-1400px
Component Spacing:
XS: 4px - Tight groups (icon + text)
S: 8px - Related items
M: 16px - Standard spacing
L: 24px - Section spacing
XL: 32px - Major sections
2XL: 48px - Page sections
Layout Patterns: See references/layout-patterns.md for grids, flexbox, and responsive patterns
Component Design
Buttons
Hierarchy:
- Primary: Filled, accent color, main action
- Secondary: Outlined or tinted, supporting action
- Tertiary: Ghost/text-only, least prominent
States:
- Default
- Hover (lift or color shift)
- Active (pressed, scale down)
- Disabled (reduced opacity, no interaction)
- Loading (spinner, disabled)
Sizes:
- Small: 32-36px height
- Medium: 40-44px height (default)
- Large: 48-56px height
Best Practices:
- Minimum 44×44px touch target (mobile)
- Clear, action-oriented labels ("Save Changes" not "OK")
- Loading state for async actions
- Icon + text for clarity
Forms
Input Fields:
- Clear labels above fields
- Placeholders as hints, not labels
- Visible focus states
- Inline validation
- Error messages near field
- Success states
Field Sizing:
- Single line: 40-48px height
- Text area: 80-120px min height
- Width matches expected input length
Form Layout:
- Single column for simplicity
- Group related fields
- Progressive disclosure (show complexity as needed)
- Save button at bottom, clear/cancel secondary
Best Practices: See references/forms.md for validation patterns and accessibility
Cards
Anatomy:
- Border radius: 8-12px (modern), 0px (brutalist)
- Padding: 16-24px
- Shadow: Subtle, 1-2 layers max
- Background: Slightly elevated from page
Types:
- Flat: No shadow, border only
- Elevated: Subtle shadow
- Interactive: Hover lift, clickable
- Glassmorphic: Blur + transparency
Content:
- Image/icon at top (optional)
- Title (heading level)
- Description/body
- Actions at bottom
Navigation
Patterns:
- Top Nav: Global, persistent (web)
- Tab Bar: 3-5 primary sections (mobile)
- Sidebar: Complex apps, collapsible (desktop)
- Hamburger: Mobile fallback, avoid if possible
- Breadcrumbs: Hierarchical location
Mobile Navigation:
- Bottom tab bar (thumb-friendly)
- Burger menu for overflow
- Sticky header with back button
Desktop Navigation:
- Top bar or sidebar
- Dropdown menus for hierarchy
- Search prominent
See references/navigation-patterns.md
Animation & Motion
Durations:
- Quick: 100-200ms (button press, hover)
- Standard: 200-400ms (transitions, sheets)
- Slow: 400-600ms (page transitions, complex)
Easing Functions:
- ease-out: Most animations (starts fast, ends slow)
- ease-in: Exits (starts slow, accelerates)
- ease-in-out: Balanced (smooth start and end)
- spring: Natural, playful (CSS or JS springs)
Animation Principles:
- Anticipation: Hint at upcoming change
- Follow-through: Motion completes naturally
- Continuity: Elements smoothly transition
- Responsive: Immediate feedback to interaction
Micro-interactions:
button: 150ms [scale: 1→0.95→1] (press)
hover: 200ms [translateY: 0→-2px] + shadow↗
fadeIn: 400ms [opacity: 0→1, translateY: 20→0]
slideIn: 300ms [translateX: -100%→0]
Reduce Motion:
- Provide crossfade alternative
- Respect
prefers-reduced-motion - Essential animations only
See references/animation-guide.md for complete animation patterns
Modern Design Trends
Dark Mode
Design Strategy:
- Test both modes simultaneously
- Use semantic colors (auto-adapt)
- Elevate surfaces with subtle lightening
- Avoid pure black (#000), use dark grays
Color Mapping:
/* Light mode */
--background: oklch(1 0 0);
--surface: oklch(0.98 0 0);
--text: oklch(0.15 0 0);
/* Dark mode */
--background: oklch(0.145 0 0);
--surface: oklch(0.205 0 0);
--text: oklch(0.985 0 0);
See references/dark-mode.md
Glassmorphism
Recipe:
.glass {
background: rgba(255, 255, 255, 0.1);
backdrop-filter: blur(10px);
border: 1px solid rgba(255, 255, 255, 0.2);
box-shadow: 0 8px 32px rgba(0, 0, 0, 0.37);
}
When to use:
- Overlays (modals, tooltips)
- Navigation bars
- Cards on rich backgrounds
- Modern, premium feel
Avoid:
- Overuse (becomes gimmicky)
- Performance-sensitive contexts
- Insufficient browser support
Neo-Brutalism
Characteristics:
- Harsh shadows (4px 4px 0 black)
- Bold, saturated colors
- Black borders (2-3px)
- Zero border radius
- Raw, unpolished aesthetic
When to use:
- Playful, creative brands
- Youth-targeted products
- Art/design portfolios
- Standing out from "clean" minimalism
See references/design-trends.md for more trends
Responsive Design
Breakpoints:
Mobile: < 640px
Tablet: 640px - 1024px
Desktop: 1024px - 1440px
Wide: > 1440px
Mobile-First Strategy:
/* Base: Mobile */
.container { padding: 16px; }
/* Tablet */
@media (min-width: 640px) {
.container { padding: 24px; }
}
/* Desktop */
@media (min-width: 1024px) {
.container {
padding: 32px;
max-width: 1200px;
margin: 0 auto;
}
}
Responsive Patterns:
- Stack → Sidebar: Single column mobile, sidebar desktop
- Grid Columns: 1 → 2 → 3 → 4 columns
- Hide/Show: Progressive disclosure
- Reorder: Priority changes by screen size
See references/responsive-design.md
