Design Best Practices
Visual Hierarchy
1. SIZE
Large = Important
Small = Less important
2. COLOR
High contrast = Attention
Low contrast = Secondary
3. POSITION
Top/Left = Primary (in LTR languages)
Bottom/Right = Secondary
4. SPACING
More space = Emphasis
Tight spacing = Related items
5. TYPOGRAPHY
Bold = Important
Regular = Body
Light = Subtle
Layout Principles
8-Point Grid System
Use multiples of 8 for:
- Spacing (8px, 16px, 24px, 32px, 40px, 48px)
- Element sizes
- Layout dimensions
Benefits:
- Consistency
- Easier handoff to developers
- Scales well for different densities
The 60-30-10 Color Rule
60% - Dominant color (background, main areas)
30% - Secondary color (supporting elements)
10% - Accent color (CTAs, highlights)
F-Pattern and Z-Pattern
F-Pattern (content-heavy pages):
- Users scan top to bottom
- Focus on left side
- Horizontal movements decrease down page
Z-Pattern (simple layouts):
- Start top-left
- Scan to top-right
- Diagonal to bottom-left
- End at bottom-right (CTA)
Mobile Design Guidelines
Touch Target Sizes
Minimum: 44x44 px (iOS), 48x48 dp (Android)
Recommended: 56-60px for primary actions
Spacing: 8px minimum between targets
Safe Areas
iOS:
- Top safe area: Below notch/status bar
- Bottom safe area: Above home indicator
Android:
- Top: Below status bar
- Bottom: Above navigation bar
Add padding to avoid system UI overlap
Mobile Navigation Patterns
1. Tab Bar (Bottom)
- 3-5 primary sections
- Always visible
- Icons + labels
2. Hamburger Menu
- More options
- Hidden by default
- Consider discoverability
3. Bottom Sheet
- Contextual actions
- Easy thumb reach
- Swipe to dismiss
Form Design Best Practices
1. ALIGNMENT
✅ Top-aligned labels (fastest completion)
⚠️ Left-aligned (takes more space)
❌ Placeholder-only (accessibility issues)
2. FIELD LENGTH
Match field length to expected input
- Phone: Shorter field
- Email: Medium field
- Address: Longer field
3. INPUT TYPES
Use appropriate HTML input types:
- email, tel, number, date
- Triggers correct keyboard on mobile
4. VALIDATION
✅ Inline validation (real-time feedback)
✅ Success indicators
✅ Clear error messages
❌ Validation only on submit
5. REQUIRED FIELDS
✅ Mark required fields (*)
✅ Or mark optional fields
✅ Explain why information is needed
6. PROGRESS INDICATORS
For multi-step forms:
- Show current step
- Show total steps
- Allow navigation between steps
7. AUTOFILL & AUTOCOMPLETE
- Use autocomplete attributes
- Support browser autofill
- Provide suggestions when helpful
Button Design Guidelines
BUTTON HIERARCHY
Primary Button:
- High contrast
- Solid fill
- One per screen/section
- For main action
Secondary Button:
- Medium contrast
- Outline or ghost
- Supporting actions
Tertiary Button:
- Text/link style
- Low priority actions
BUTTON STATES
Default → Hover → Active → Disabled
Each state should be visually distinct:
- Hover: Slight color change
- Active: Pressed appearance
- Disabled: Reduced opacity (40-60%)
BUTTON SIZE
Large: 48-56px height (mobile primary actions)
Medium: 40-44px height (default)
Small: 32-36px height (secondary actions)
BUTTON LABELS
✅ Action-oriented ("Save changes", "Create account")
✅ Specific ("Delete file", not just "Delete")
❌ Generic ("Click here", "Submit")
Design by Component
Navigation Design
Primary Navigation
Desktop:
- Horizontal top bar
- 5-7 main items
- Dropdown menus for sub-items
- Search prominent
Mobile:
- Bottom tab bar (iOS)
- Top app bar + hamburger (Android)
- 4-5 items max in tab bar
Breadcrumbs
Usage:
- 3+ levels deep
- E-commerce, documentation
- Not for single-path flows
Format:
Home > Category > Subcategory > Current Page
Guidelines:
- Make all levels clickable (except current)
- Use chevron separator (>)
- Truncate on mobile
Card Design
Card Anatomy:
┌─────────────────────────┐
│ [Image/Thumbnail] │
├─────────────────────────┤
│ Title │
│ Description │
│ Metadata (date, author)│
│ [Action Button] │
└─────────────────────────┘
Best Practices:
- Consistent card sizes
- Clear visual hierarchy
- Adequate padding (16-24px)
- Hover state for interactivity
- Shadow or border for definition
Modal Design
Modal Guidelines:
SIZE:
- Small: 400px width (confirmations)
- Medium: 600px width (forms)
- Large: 800px+ width (complex content)
STRUCTURE:
┌─────────────────────────────┐
│ Title [×]│
├─────────────────────────────┤
│ │
│ Content │
│ │
├─────────────────────────────┤
│ [Cancel] [Primary] │
└─────────────────────────────┘
BEHAVIOR:
- Click outside to close (or not, for critical actions)
- ESC key to close
- Focus trap (keyboard navigation)
- Prevent body scroll
- Return focus on close
ALTERNATIVES TO CONSIDER:
- Inline expansion
- Side panel
- Bottom sheet (mobile)
- Toast notification
Empty States
Empty State Components:
1. Icon/Illustration
2. Headline (what's empty)
3. Description (why it's empty)
4. Call-to-action (what to do)
Examples:
NO ITEMS:
"No messages yet"
"Start a conversation with your team"
[+ New Message]
NO RESULTS:
"No results found for 'search term'"
"Try different keywords or filters"
[Clear Filters]
NO CONNECTION:
"You're offline"
"Check your internet connection"
[Try Again]

Screen Reader Considerations
Semantic HTML:
<header>, <nav>, <main>, <aside>, <footer>
<h1> to <h6> (proper hierarchy)
<button>, <a>, <input>, <label>
ARIA Labels:
- aria-label: Direct label
- aria-labelledby: Reference to label element
- aria-describedby: Additional description
- role: Define element purpose
- aria-live: Announce dynamic content
Example:
<button
aria-label="Close dialog"
aria-describedby="close-help">
×
</button>
<span id="close-help" hidden>
Press Escape to close
</span>
