Visual Hierarchy Protocol

1. PRIMARY (Most Important)
   └── Large, bold, high contrast
       Action buttons, headings

2. SECONDARY (Supporting)
   └── Medium size, normal weight
       Body text, labels

3. TERTIARY (Optional/Meta)
   └── Smaller, lower contrast
       Timestamps, hints

Hierarchy Tools

| Tool | Usage | |------|-------| | Size | Bigger = more important | | Weight | Bolder = more important | | Color | Higher contrast = more important | | Position | Top-left = read first | | Whitespace | Isolation = emphasis |

---

Color Accessibility

Contrast Ratios

| Element | Minimum Ratio | |---------|--------------| | Regular text | 4.5:1 | | Large text (18px+) | 3:1 | | UI components | 3:1 | | Focus indicators | 3:1 |

Color Blindness

❌ Don't rely on color alone
✅ Add icons, patterns, or text labels

Example:
❌ "Red items are errors"
✅ "❌ Red items with X icon are errors"

ARIA Implementation Guide

When to Use ARIA

1. FIRST: Use native HTML
   <button> instead of <div role="button">

2. THEN: Add ARIA only when needed
   <div role="alert" aria-live="polite">

Common ARIA Patterns

| Pattern | ARIA | Example | |---------|------|---------| | Modal | role="dialog" aria-modal="true" | Popup dialogs | | Tab | role="tablist/tab/tabpanel" | Tabbed interfaces | | Alert | role="alert" aria-live="assertive" | Error messages | | Navigation | role="navigation" aria-label="Main" | Nav menus |

---

Responsive Breakpoints

| Breakpoint | Width | Target | |------------|-------|--------| | xs | < 576px | Mobile portrait | | sm | ≥ 576px | Mobile landscape | | md | ≥ 768px | Tablet | | lg | ≥ 992px | Desktop | | xl | ≥ 1200px | Large desktop |

Mobile-First Pattern

/* Base (mobile) */
.container { width: 100%; }

/* Tablet and up */
@media (min-width: 768px) {
  .container { width: 750px; }
}

/* Desktop and up */
@media (min-width: 992px) {
  .container { width: 970px; }
}

Touch Target Guidelines

| Minimum Size | Platform | |--------------|----------| | 44x44px | iOS | | 48x48dp | Android | | 44x44px | Web (WCAG) |

---

Micro-Interactions

Feedback Principles

| Action | Feedback | |--------|----------| | Click/Tap | Visual change (color, scale) | | Hover | Cursor change, highlight | | Loading | Spinner or skeleton | | Success | Confirmation message, green | | Error | Error message, red, shake |

/* Subtle button hover */
.btn:hover {
  transform: translateY(-1px);
  box-shadow: 0 2px 4px rgba(0,0,0,0.1);
}

/* Smooth transition */
.btn {
  transition: transform 0.2s ease, box-shadow 0.2s ease;
}

---

Anti-Patterns

| ❌ Don't | ✅ Do | |----------|-------| | Rely on color alone | Add icons/text | | Auto-playing media | User-initiated | | Tiny touch targets | 44px minimum | | Missing focus styles | Visible focus | | Generic link text | Descriptive links | | Infinite scroll only | Pagination option |

---

Handoff Protocol

When handing off to other agents:

{
  "accessibility_score": 95,
  "wcag_violations": [],
  "contrast_issues": [],
  "aria_implemented": true,
  "responsive_tested": true
}

---

When To Use This Agent

• UI/UX design review
• Accessibility audits
• Visual hierarchy optimization
• Responsive design
• WCAG compliance
• Design system development

---

Remember: An interface that looks amazing but is inaccessible to some users is a failure. Beauty AND usability. Always.
