A global, accessible, and themeable design system for the web platform.

The OpenUI Design System is a collaborative effort to create a centralized set of UI components that can be used across the web. It aims to:

• Provide high-quality, accessible components that work across any web framework
• Reduce duplicative effort in rebuilding common UI patterns
• Improve the overall quality and accessibility of web experiences
• Create a bridge between low-level HTML elements and organization-specific design systems and individual web products
• Serve as an incubator for potential future HTML elements, attributes and APIs.

The OpenUI Design System provides Web Components that are:

• Framework-agnostic
• Highly accessible by default
• Completely themeable
• Internationalized
• Composable and extensible
• Built on web standards
• Meet a high bar of quality based on thorough criteria
• Rigorously tested and reviewed by experts in accessibility, internationalization, security, and front-end development.

• A replacement for HTML - The OpenUI Design System builds on top of HTML elements rather than replacing them.
• A W3C Standard - The OpenUI Design System is an incubation for possible future enhancements to the web platform but they are not standardized components
• A visual design language - Components are intentionally unstyled by default, which allows users to incorporate their own visual design via the design token system.
• A comprehensive solution for all UI needs - The OpenUI Design System focuses on common, well-established patterns, and does not attempt to cover every possible UI component and variant.
• A corporate product - This is a community effort meant to transcend any one organization's walls and truly meet the common needs of the world's web community.

Note: The OpenUI Design System is not yet available, but the following captures the spirit of what this project aims to provide.

npm install @openui/design-system

<script
  type="module"
  src="node_modules/@openui/design-system/dist/openui.js"
></script>

<oui-text-field label="Email Address" type="email" required> </oui-text-field>

<oui-button variant="primary">Submit</oui-button>

OpenUI Design System components ship with minimal default styling and can be themed using a robust design token system that is powered by CSS custom properties:

:root {
  --oui-primary-color: #0066cc;
  --oui-border-radius: 4px;
  --oui-font-family: system-ui, sans-serif;
}

We welcome contributions from the community! Here's how you can help:

1. Submit a proposal for a component to be included in the OpenUI Design System
2. Open an issue
3. Participate in discussions about the component's API and behavior
