- Accessibility baked-in – All HDS components are designed from the ground up to be as accessible as possible. Components go through a third-party accessibility audit before release.
- React & CSS – Components are available both as React and CSS styles. Choose the one which suits best for your project.
- Customizable – HDS components are designed to be customizable to allow expressing the vibrant Helsinki brand.
- Design and Implementation in sync – Designers use a collection of Sketch libraries which are perfectly in sync with the implementation.
HDS is divided into three (3) separate packages:
– Helsinki City brand colors, typography and base styles as css-styles and variables
– Provides HDS components implemented using React
– Basis of the HDS which includes base colors, typography etc. as design tokens.

Helsinki Design System uses Lerna for running scripts across the repo as well as versioning and creating releases of the packages. Yarn workspaces is used to manage dependencies. This allows the separate packages to reference each other via symlinks during local development.
See the package specific instructions on how to get started using the packages.
Start setting up your local development by going through the steps in the development guide.
