UI UX Audit

UI/UX Audit - Interface Audit System

Purpose

This skill automates UI/UX audits:

• Research competitors before implementing
• Validate accessibility (WCAG, contrast, touch targets)
• Verify responsiveness
• Audit design system consistency
• Document design decisions

Workflow

1. IDENTIFY FEATURE → What type of UI? Mobile-first or desktop-first?
        ↓
2. RESEARCH COMPETITORS → 3-5 relevant competitors, screenshots
        ↓
3. DEFINE PATTERN → What do all do alike? Where to differentiate?
        ↓
4. IMPLEMENT → Follow accessibility and responsiveness checklists
        ↓
5. VALIDATE → Run final checklist, capture screenshots

Accessibility Checklist (WCAG 2.1)

Level A (Required)

• Text contrast: Minimum 4.5:1 normal, 3:1 large text
• Alt text: All images have descriptive alt
• Keyboard navigation: All interactive elements via Tab
• Visible focus: Clear outline on focused elements
• Form labels: All inputs have associated label
• Error messages: Clear and associated to field

Level AA (Recommended)

• Resize: Works up to 200% zoom
• Touch targets: Minimum 44x44px (h-11 w-11)
• Hover/Focus: Content visible on hover also via focus

Responsiveness Checklist

Required Viewports

const REQUIRED_VIEWPORTS = {
	mobile: { width: 375, height: 667 }, // iPhone SE
	tablet: { width: 768, height: 1024 }, // iPad
	desktop: { width: 1280, height: 800 }, // Laptop
	fullhd: { width: 1920, height: 1080 }, // Common monitor
};

Mobile (375px)

• Vertical stack layout (flex-col)
• Hamburger menu or bottom nav
• Touch-friendly buttons (min 44px)
• Readable text without zoom
• Vertical scroll only

Desktop (1280px+)

• Use horizontal space
• Expanded sidebar
• Can increase info density

CRITICAL: Zero Horizontal Overflow

NEVER should there be horizontal scroll.

Required CSS Patterns

// Main layout
<div className="flex h-screen w-screen overflow-hidden">
	{/* Sidebar */}
	<aside className="w-[260px] flex-shrink-0 overflow-y-auto">...</aside>

	{/* Main content */}
	<main className="flex-1 min-w-0 overflow-hidden">...</main>
</div>

Overflow Checklist

• Main container has overflow-hidden?
• Sidebar has flex-shrink-0?
• Main content has min-w-0?
• No element with width larger than container?
• Tested at 1920x1080?

Skeleton Loading

Rule: Every Component HAS Skeleton

• Skeleton created with component
• Same dimensions as final content
• animate-pulse animation
• Same visual structure

Structure

components/features/UserCard/
├── UserCard.tsx
└── UserCardSkeleton.tsx

Template

export function ComponentSkeleton() {
	return (
		<div className="animate-pulse">
			<div className="h-4 bg-gray-200 rounded w-3/4 mb-2" />
			<div className="h-4 bg-gray-200 rounded w-1/2" />
		</div>
	);
}

Design System (Tailwind)

Colors

• Primary: indigo-600 (buttons, links)
• Secondary: gray-600 (secondary text)
• Success: green-600
• Error: red-600
• Warning: yellow-600

Spacing (4px scale)

p-1: 4px    p-2: 8px    p-4: 16px
p-6: 24px   p-8: 32px   p-12: 48px

Border & Shadow

• Border radius: rounded-lg (8px) default
• Shadows: shadow-sm for cards, shadow-lg for modals
