About

Fluent Design System is Microsoft's cross-platform design language that defines how user interfaces should look and behave across Windows, web, and mobile applications.

It uses a unified set of design tokens for colors, spacing, icons, and typography, and supports adaptive layouts for different screen sizes.

The U.S. Web Design System (USWDS) is an open-source design system developed by the United States government to help federal agencies build fast, accessible, and mobile-friendly websites.

It provides a library of reusable UI components, design patterns, and production-ready code with built-in compliance for standards such as Section 508 and the 21st Century IDEA, along with utilities, templates, and standardized design variables for color, typography, and spacing.
