20 October 2023: The Defence Developer Services (D2S) will shortly commence work on its re-use strategy and the discovery and delivery of a re-use components service. As part of this, we will commence a Discovery activity for the Design System Toolkit. During the Discovery Phase, the MOD.UK Frontend and Design Library will be in maintenance mode with no further enhancements being made during this time. Only high priority issues such as security fixes or outages will be completed.

MOD.UK Frontend contains the code for components you’ll need to build user interfaces for Defence products and services.

See guidance on the components with coded examples.

You can report bugs or request new features.

Email design-system@digital.mod.uk if you have questions or any feedback. Please share examples of how you are using MOD.UK Frontend.

You need to install MOD.UK Frontend to use the components in the MOD.UK Design System in your production environment.

See setup guide for developers which shows you how to start using MOD.UK Frontend.

Design and prototype your Defence project with our component design library in Figma.

MOD.UK Frontend aims to support:

• recommended browsers
• recommended assistive technologies
• your users overriding colours in Windows, Firefox and Chrome

Using MOD.UK Frontend will help your service meet level AA of WCAG 2.1. But you must still check that your service meets accessibility requirements, especially if you extend or modify components.

You should also use the JavaScript from MOD.UK Frontend.

If you get a warning from a linter or accessibility checker, check a list of issues you should not need to fix.

To be notified when there’s a new release you can watch the moduk-frontend repository. (After selecting ‘Watch’, choose the ‘Custom’ option and select ‘Releases’.)

If you have found a security vulnerability, please let us know so we can fix it.

Report a vulnerability on an MOD system.
