ancoleman/theming-components
Provides design token system and theming framework for consistent, customizable UI styling across all components. Covers complete token taxonomy (color, typography, spacing, shadows, borders, motion, z-index), theme switching (CSS custom properties, theme providers), RTL/i18n support (CSS logical properties), and accessibility (WCAG contrast, high contrast themes, reduced motion). This is the foundational styling layer referenced by ALL component skills. Use when theming components, implementing light/dark mode, creating brand styles, customizing visual design, ensuring design consistency, or supporting RTL languages.

Comprehensive design token system providing the foundational styling architecture for all component skills, enabling brand customization, theme switching, RTL support, and consistent visual design.
Design tokens are the single source of truth for all visual design decisions. This skill provides:
Critical Architectural Principle:
Component Skills (Behavior + Structure) → Use tokens for ALL visual styling
Design Tokens (Styling Variables) → Define colors, spacing, typography
Theme Files (Token Overrides) → Light, dark, brand-specific values
Step 1: Reference tokens in your component:
.button {
background-color: var(--button-bg-primary);
color: var(--button-text-primary);
padding-inline: var(--button-padding-inline);
padding-block: var(--button-padding-block);
border-radius: var(--button-border-radius);
transition: var(--transition-fast);
}
Step 2: Themes automatically apply:
<!-- Light theme -->
<html data-theme="light">
<button class="button">Primary Button</button>
</html>
<!-- Dark theme (same component, different appearance) -->
<html data-theme="dark">
<button class="button">Primary Button</button>
</html>
No code changes needed - theme switching is automatic!
function setTheme(themeName) {
document.documentElement.setAttribute('data-theme', themeName);
localStorage.setItem('theme', themeName);
}
function toggleTheme() {
const current = document.documentElement.getAttribute('data-theme');
setTheme(current === 'dark' ? 'light' : 'dark');
}
// Load saved theme on page load
setTheme(localStorage.getItem('theme') || 'light');
3-tier hierarchy: Primitive → Semantic → Component
/* Primitive (9-shade scales) */
--color-blue-500: #3B82F6;
/* Semantic (purpose-based) */
--color-primary: var(--color-blue-500);
--color-success: var(--color-green-500);
--color-error: var(--color-red-500);
/* Component-specific */
--button-bg-primary: var(--color-primary);

Use logical properties for automatic RTL language support:
| Physical (Avoid) | Logical (Use) |
|------------------|---------------|
| margin-left | margin-inline-start |
| padding-right | padding-inline-end |
| text-align: left | text-align: start |
/* Correct - auto-flips in RTL */
.button {
padding-inline: var(--button-padding-inline);
margin-inline-start: var(--spacing-sm);
}
Complete RTL guide: See references/logical-properties.md
All component skills use this naming convention:
--{component}-{property}-{variant?}-{state?}
Examples:
--button-bg-primary
--button-bg-primary-hover
--input-border-color-focus
--chart-color-1
Components use tokens for ALL styling:
.button {
background-color: var(--button-bg-primary);
border-radius: var(--button-border-radius);
}
Theme changes automatically update all components.

:root[data-theme="high-contrast"] {
--color-primary: #0000FF;
--color-text-primary: #000000;
/* 7:1 contrast (WCAG AAA) */
}
@media (prefers-reduced-motion: reduce) {
:root {
--duration-fast: 0ms;
--transition-fast: none;
}
}

JSON Tokens → Style Dictionary → CSS Variables
→ iOS Swift
→ Android XML
→ JavaScript
