DB UI Mono provides robust HTML UI components, reusable visual styles, and powerful tooling to help developers, designers, and content authors build, maintain, and scale best of class digital experiences.
We’re not designing pages anymore. We’re designing systems of components. Stephen Hay. Cited in a talk by Brad Frost at beyond tellerrand conference.| Package | Content | Version |
|---|---|---|
| foundations | CSS/SCSS/Tailwind styles and assets |  |
| components | CSS/SCSS styles for components | |
| ngx-components | Native Angular components | |
| react-components | Native React components | |
| v-components | Native Vue 3 components | |
| web-components | Web Components | |
Install your preferred package via npm or yarn e.g. npm i @db-ui/react-components.
Afterwards you need to add the specific CSS or SCSS files to provide the styles of DB UX Design System. For a detailed overview look at our examples.
We maintain a status overview for all components.
Consistent & Compliant
DB UI Mono is part of DB UX Design System Core, that are the guidelines for any Personenverkehr Customer and Deutsche Bahn Enterprise website and web applications.
Accessible
DB UI Mono leverages semantic HTML, ARIA roles, states and properties to apply our styles wherever possible, thus enforcing correct, accessible markup. And we're quality checking this in partnership with the Team Digital Accessibility.
Declarative
DB UI Mono uses declarative selectors instead of visual helpers to ensure our HTML class names and structure are human read- and understandable, lean, performant and so much easier to update.
Evergreen
As DB UX Design System evolves, so does DB UI Mono, meaning apps only need to keep their DB UI Mono package updated to ensure the latest look and feel.
This is mainly a platform providing the space and technology for a common basis of curated components; their development is mainly driven by the community and adapted out of the work done in projects and through the huge amount of feedback that we're gaining out of the community. So please support us in any way possible, this is greatly appreciated!
We're providing a detailed migration for each component next to the documentation of each component: https://db-ui.github.io/mono/review/main/components/action/button/migration
Check our migration docs for breaking changes:
- Alpha ➡ Beta (0.0.x➡0.x.x)
- v0.2 ➡ v0.3
- v0.3 ➡ v0.4
- v0.4 ➡ v0.5: no migration needed, no breaking changes
- v0.5 ➡ v0.6

All versions in all package.json files are set to 0.0.0, we change those during release process in CI/CD.
This is only the first version of our framework and we really want your feedback - either within the DB UI Channel by Web Dev Community in Microsoft Teams (only available DB internally), or directly at [email protected]. We're particularly keen to add as many examples to the behaviours as possible, to further clarify them.
