Welcome to Functional UI Kit

Functional UI Kit is a professionally crafted UI Kit for design & development teams, and individuals. We provide core components you would need in every project, focusing on accessibility, development experience and unified designer-developer experience.

We've made sure that Figma variables and CSS variables work together effortlessly. They share the same names, usage and inheritance structure. This isn't just an extra feature, it's the core approach.

Each Figma variable has a direct counterpart in CSS, so there's no confusion. The design stays crystal clear as you move into the development phase.
