Welcome to KoliBri
"The accessible HTML standard"
KoliBri is not a design system in the traditional sense. Rather, we extend the HTML5 standard with self-contained, accessible Web Components — new HTML elements that work independently from any design or branding. These atomic components form a foundation that any design library, framework, or style guide can reuse and theme according to their needs.
KoliBri stands for "component library for accessibility" and was released as open source by the Informationstechnikzentrum Bund (ITZBund) for reuse and continued development.
Vision
Together we make HTML accessible using reusable web components to ensure usability and accessibility.
Mission
The HTML web standard is itself very “openly” specified in order to be as long-lasting and robust as possible. It therefore often happens that HTML compositions are not easily accessible, semantic and valid.
KoliBri is based directly on the Web standards of the W3C (framework-agnostic), and is generic Reference implementation of the WCAG standard and the BITV for accessibility and implemented as a multi-theming capable presentation layer. There is no technical reference and no data transfer functionality. This means that KoliBri is equally reusable for the realization of static websites as well as dynamic web applications with different corporate designs and style guides and is therefore very interesting for open source.
