Hello @andrico1234,

could you review this PR?

[andrico1234]

Thanks for contributing the Kolibri to the Open UI design system catalog

As per the Open UI site, a design system added to the site should satisfy many of the following points:

✅ support designers and developers
✅ support multiple platforms and frameworks
✅ support accessible users
✅ support small and enterprise projects
✅ demonstrate organic adoption in a wide community
✅ demonstrate significant real-world usage
✅ demonstrate deep thought and debate by many experienced minds

Are you able to provide a few short sentences on how Kolibri satisfies the above criteria?

I'll be happy to approve after 😄

@andrico1234 We have answered ;-).

✅ support designers and developers

We have developed an accessible Web Component Lib, where the semantic HTML is completely decoupled from the design CSS.
For developers, the small-part Web Components are interesting, which can be reused virtually in any other design system.
For designers it is exciting, because they can create so called themes on the accessible components. The advantage is the maximum freedom with CSS - instead of depending only on CSS properties or design tokens.

✅ support multiple platforms and frameworks

Yes, by means of the Web Components we support all modern platforms and frameworks (Pure HTML, React, Preact, Angular, Solid, Next.js, Astro, etc.).

See: https://public-ui.github.io/?path=/docs/frameworks--page

✅ support accessible users

This is our vision. We've built the whole lib from the ground up, starting with accessibility requirements, not design. All. Everything we do starts with the question: Is this accessible? And then we continue to look at how granular and flexible it can be reused. Design comes much later.

✅ support small and enterprise projects

Our lib is suitable for the implementation of any size project.

✅ demonstrate organic adoption in a wide community

Our lib is used to implement web-based citizen services of all types in Germany. The lib is published under the EUPL 1.2 of the European Union.

✅ demonstrate significant real-world usage

Our mission: The HTML web standard is specified very "openly" in order to be as durable and robust as possible. Therefore, it often happens that HTML compositions are not easily accessible, semantic and valid. KoliBri builds directly on the web standards of the W3C (framework-agnostic), is a generic reference implementation of the WCAG standard and the BITV for accessibility and implemented as a multi-theme capable presentation layer. There is no technical reference and no data transfer functionalities. This makes KoliBri equally reusable for the realization of static websites as well as dynamic web applications of different corporate designs and style guides and therefore very interesting for open source.

There are more and more laws coming in the future to improve accessibility. On for the private sector.

✅ demonstrate deep thought and debate by many experienced minds

Our library was developed by a broad team of architects, accessibility experts and UX designers over now more than 2,5 years. The ITZBund is maintainer of the lib in the whole community.

Thanks and We wish you a Merry Christmas 🎄.
