vaadin/web-componentsmonorepository. This repository contains the source code and releases of
@vaadin/vaadin-lumo-stylesfor the Vaadin versions 10 to 19.
Lumo is a design system foundation for modern, beautiful and accessible web applications.

Lumo contains foundational styles – typography, colors, visual style, sizing & spacing and icons – that components and applications can use to achieve a consistent visual design.
The implementation of Lumo is based on CSS custom properties, and Polymer style modules. Note, that you don’t need to use Polymer to build your application in order to use Lumo.
