What is Material Design 3?

Material Design 3 is Google's open-source design system for creating digital products. It has evolved through two major phases:

Material You (M3 Baseline)

The foundational M3 system introduced:

• Dynamic Color: Adaptive themes derived from user wallpapers and preferences
• Tonal Palettes: Five key palettes with systematic tonal generation
• Type Scale: 15 baseline type styles across five roles
• Shape System: Semantic corner radius scale from none to full
• Elevation System: Five levels with tinting for depth
• Component Library: Complete set of accessible, themed components
• Token System: CSS custom properties for consistent theming

M3 Expressive (Latest Evolution)

Building on Material You, M3 Expressive adds:

• 30-Style Type Scale: 15 emphasized variants alongside the 15 baseline styles
• 35 Expressive Shapes: Decorative shape library with smooth morphing
• Physics-Based Motion: Spring parameters (stiffness, damping, velocity) replacing traditional easing
• Fixed Accent Colors: Colors that stay constant across light and dark themes
• Contrast Levels: Standardized standard, medium, and high contrast modes
• New Components: Split buttons, button groups, floating toolbars, FAB menus
• Background Blur: Depth effects for overlays and navigation
• Haptic Integration: Coordinated vibration with spring animations

The Seven Pillars of Material Design 3

Material Design 3 is built on seven interconnected design pillars:

1. Color and Dynamic Theming

Integration Principles

All Skills Work Together

Material Design 3 is a holistic system - the skills are designed to be used together:

• Color defines the palette
• Typography defines the text
• Shape defines the form
• Motion defines the behavior
• Layout defines the structure
• Components define the building blocks
• Icons define the visual language

Consistency is Key

When using multiple skills:

• Use tokens/variables defined in each skill
• Don't hard-code values
• Maintain consistency across all design aspects
• Test the combined result, not just individual parts

Example: Complete Button Implementation

/* Uses all seven pillars */
.md3-button {
  /* Shape */
  border-radius: var(--md-sys-shape-corner-full);
  
  /* Color */
  background-color: var(--md-sys-color-primary);
  color: var(--md-sys-color-on-primary);
  
  /* Typography */
  font-family: var(--md-sys-typescale-label-large-font);
  font-size: var(--md-sys-typescale-label-large-size);
  font-weight: var(--md-sys-typescale-label-large-weight);
  letter-spacing: var(--md-sys-typescale-label-large-tracking);
  
  /* Layout */
  padding: var(--md-sys-spacing-2) var(--md-sys-spacing-6);
  min-height: 40px;
  display: inline-flex;
  align-items: center;
  gap: var(--md-sys-spacing-2);
  
  /* Motion */
  transition: 
    background-color var(--md-sys-motion-duration-short2) var(--md-sys-motion-easing-standard),
    box-shadow var(--md-sys-motion-duration-short2) var(--md-sys-motion-easing-standard),
    transform var(--md-sys-motion-duration-short2) var(--md-sys-motion-easing-standard);
}

.md3-button:hover {
  /* Color - state layer */
  background-color: var(--md-sys-color-primary);
  box-shadow: 0 2px 4px rgba(0,0,0,0.1);
  
  /* Motion */
  transform: translateY(-1px);
}

/* Icons in button */
.md3-button .material-symbols-outlined {
  font-size: 18px;
  font-variation-settings: 'opsz' 20;
}

Best Practices

Do's

1. ✅ Use all seven pillars - M3 works best when all aspects are implemented
2. ✅ Start with tokens - Define all design tokens before building components
3. ✅ Follow the skills - Each skill provides tested, research-backed guidelines
4. ✅ Test accessibility - All skills include accessibility requirements
5. ✅ Support both themes - Always implement light and dark modes
6. ✅ Use semantic names - Use token names, not hard-coded values
7. ✅ Be consistent - Apply the same patterns across all components
8. ✅ Cover the full spec - Include Material You baseline and M3 Expressive additions

Don'ts

1. ❌ Don't cherry-pick - Using only color without shape/motion isn't really M3
2. ❌ Don't hard-code - Always use the defined tokens and variables
3. ❌ Don't skip accessibility - Contrast, sizing, and motion preferences matter
4. ❌ Don't ignore dark mode - It's a core part of M3
5. ❌ Don't improvise values - Use the scales provided in each skill
6. ❌ Don't mix design systems - Don't combine M3 with other design languages
7. ❌ Don't forget motion - Static M3 misses the "expressive" part
8. ❌ Don't skip icons - Material Symbols are integral to the M3 visual language

Material Design 3 for Different Web Stacks

M3 can be implemented across many web stacks. Each framework has a dedicated library-specific skill with full setup, theming, and component examples. Use the overview table below to find the right skill for your project.

Web Stack Overview

Choosing the Right Stack

Tips for choosing:

1. Angular projects: Use m3-web-angular — best official M3 support of any web framework
2. React projects: Use m3-web-react for MUI, or m3-web-webcomponents for Google's official components
3. Vue projects: Use m3-web-vue — Vuetify 3 is mature and well-documented
4. Framework-agnostic: Use m3-web-webcomponents or m3-web-vanilla
5. Prototype quickly: Use m3-web-vanilla (Beer CSS) or m3-web-webcomponents via CDN
6. Need Tailwind: Use m3-web-tailwind to map M3 tokens to Tailwind config
7. Mobile + Web: Use m3-web-flutter for cross-platform M3
8. CLI / Terminal: Use m3-web-ink with M3 color tokens mapped to terminal colors

Summary

Material Design 3 is a complete design system covering the full specification from Material You foundations through M3 Expressive enhancements. It is built on seven interconnected pillars, each with a dedicated skill:

1. Color - The palette, themes, and accessibility
2. Motion - The behavior, physics, and haptics
3. Typography - The voice, hierarchy, and emphasis
4. Shape - The personality, form, and expression
5. Layout - The structure, depth, and containment
6. Components - The building blocks and interactions
7. Icons - The visual language and symbols

Use this guide to understand which skill to apply for your specific needs, and remember that M3 works best when all seven pillars work together in harmony.
