Build products customers love

Chi is Lumen's design system for building consistent digital products and experiences.


Chi components follow the Revised Section 508 and WCAG 2.0 AA standards which ensure the best experience is provided for all customers, including those with disabilities.


Chi components are flexible building blocks that can be implemented as is or assembled in various combinations to satisfy requirements across Consumer, Enterprise, and internal tools.


Chi provides consistent, reusable components that continuously evolve with each new release by inheriting Lumen's latest features, improvements, and brand guidelines.


Chi's framework agnostic web components and independent CSS layer are compatible with any major framework (AngularJS, ReactJS, VueJS) or no framework at all.
