UI Design Reference - Searchable Pattern Database

UI Design Reference - Searchable Pattern Database

Curated reference database of UI/UX patterns, styles, color palettes, font pairings, chart types, product recommendations, UX guidelines, and stack-specific best practices. Use this as a lookup tool to find proven design patterns and implementation guidance.

Prerequisites

Check if Python is installed:

python3 --version || python --version

If Python is not installed, install it based on user's OS:

macOS:

brew install python3

Ubuntu/Debian:

sudo apt update && sudo apt install python3

Windows:

winget install Python.Python.3.12

How to Use This Skill

When user requests UI/UX work (design, build, create, implement, review, fix, improve), follow this workflow:

Step 1: Analyze User Requirements

Extract key information from user request:

• Product type: SaaS, e-commerce, portfolio, dashboard, landing page, etc.
• Style keywords: minimal, playful, professional, elegant, dark mode, etc.
• Industry: healthcare, fintech, gaming, education, etc.
• Stack: React, Vue, Next.js, or default to html-tailwind

Step 2: Search Relevant Domains

Use search.py multiple times to gather comprehensive information. Search until you have enough context.

python3 .claude/skills/ui-ux-design/scripts/search.py "<keyword>" --domain <domain> [-n <max_results>]

Recommended search order:

1. Product - Get style recommendations for product type
2. Style - Get detailed style guide (colors, effects, frameworks)
3. Typography - Get font pairings with Google Fonts imports
4. Color - Get color palette (Primary, Secondary, CTA, Background, Text, Border)
5. Landing - Get page structure (if landing page)
6. Chart - Get chart recommendations (if dashboard/analytics)
7. UX - Get best practices and anti-patterns
8. Stack - Get stack-specific guidelines (default: html-tailwind)

Step 3: Stack Guidelines (Default: html-tailwind)

If user doesn't specify a stack, default to html-tailwind.

python3 .claude/skills/ui-ux-design/scripts/search.py "<keyword>" --stack html-tailwind

Available stacks: html-tailwind, react, nextjs, vue, svelte, swiftui, react-native, flutter

Example Workflow

User request: "Làm landing page cho dịch vụ chăm sóc da chuyên nghiệp"

AI should:

# 1. Search product type
python3 .claude/skills/ui-ux-design/scripts/search.py "beauty spa wellness service" --domain product

# 2. Search style (based on industry: beauty, elegant)
python3 .claude/skills/ui-ux-design/scripts/search.py "elegant minimal soft" --domain style

# 3. Search typography
python3 .claude/skills/ui-ux-design/scripts/search.py "elegant luxury" --domain typography

# 4. Search color palette
python3 .claude/skills/ui-ux-design/scripts/search.py "beauty spa wellness" --domain color

# 5. Search landing page structure
python3 .claude/skills/ui-ux-design/scripts/search.py "hero-centric social-proof" --domain landing

# 6. Search UX guidelines
python3 .claude/skills/ui-ux-design/scripts/search.py "animation" --domain ux
python3 .claude/skills/ui-ux-design/scripts/search.py "accessibility" --domain ux

# 7. Search stack guidelines (default: html-tailwind)
python3 .claude/skills/ui-ux-design/scripts/search.py "layout responsive" --stack html-tailwind

Then: Synthesize all search results and implement the design.

Tips for Better Results

1. Be specific with keywords - "healthcare SaaS dashboard" > "app"
2. Search multiple times - Different keywords reveal different insights
3. Combine domains - Style + Typography + Color = Complete design system
4. Always check UX - Search "animation", "z-index", "accessibility" for common issues
5. Use stack flag - Get implementation-specific best practices
6. Iterate - If first search doesn't match, try different keywords

Common Rules for Professional UI

These are frequently overlooked issues that make UI look unprofessional:

Icons & Visual Elements

Rule	Do	Don't
No emoji icons	Use SVG icons (Heroicons, Lucide, Simple Icons)	Use emojis like 🎨 🚀 ⚙️ as UI icons
Stable hover states	Use color/opacity transitions on hover	Use scale transforms that shift layout
Correct brand logos	Research official SVG from Simple Icons	Guess or use incorrect logo paths
Consistent icon sizing	Use fixed viewBox (24x24) with w-6 h-6	Mix different icon sizes randomly

Interaction & Cursor

Rule	Do	Don't
Cursor pointer	Add cursor-pointer to all clickable/hoverable cards	Leave default cursor on interactive elements
Hover feedback	Provide visual feedback (color, shadow, border)	No indication element is interactive
Smooth transitions	Use transition-colors duration-200	Instant state changes or too slow (>500ms)

Light/Dark Mode Contrast

Rule	Do	Don't
Glass card light mode	Use bg-white/80 or higher opacity	Use bg-white/10 (too transparent)
Text contrast light	Use #0F172A (slate-900) for text	Use #94A3B8 (slate-400) for body text
Muted text light	Use #475569 (slate-600) minimum	Use gray-400 or lighter
Border visibility	Use border-gray-200 in light mode	Use border-white/10 (invisible)

Layout & Spacing

Rule	Do	Don't
Floating navbar	Add top-4 left-4 right-4 spacing	Stick navbar to top-0 left-0 right-0
Content padding	Account for fixed navbar height	Let content hide behind fixed elements
Consistent max-width	Use same max-w-6xl or max-w-7xl	Mix different container widths

Pre-Delivery Checklist

Before delivering UI code, verify these items:

Visual Quality

• No emojis used as icons (use SVG instead)
• All icons from consistent icon set (Heroicons/Lucide)
• Brand logos are correct (verified from Simple Icons)
• Hover states don't cause layout shift
• Use theme colors directly (bg-primary) not var() wrapper

Interaction

• All clickable elements have cursor-pointer
• Hover states provide clear visual feedback
• Transitions are smooth (150-300ms)
• Focus states visible for keyboard navigation

Light/Dark Mode

• Light mode text has sufficient contrast (4.5:1 minimum)
• Glass/transparent elements visible in light mode
• Borders visible in both modes
• Test both modes before delivery

Layout

• Floating elements have proper spacing from edges
• No content hidden behind fixed navbars
• Responsive at 320px, 768px, 1024px, 1440px
• No horizontal scroll on mobile

Accessibility

• All images have alt text
• Form inputs have labels
• Color is not the only indicator
• prefers-reduced-motion respected
