GOV.UK Frontend contains the code you need to start building a user interface for government platforms and services.
See live examples of GOV.UK Frontend components, and guidance on when to use them in your service, in the GOV.UK Design System.
GOV.UK Frontend is maintained by a team at Government Digital Service. If you want to know more about GOV.UK Frontend, please email the Design System team or get in touch with them on Slack.
There are 2 ways to start using GOV.UK Frontend in your app.
Once installed, you will be able to use the code from the examples in the GOV.UK Design System in your service.
We recommend installing GOV.UK Frontend using node package manager (npm).
You can also download the compiled and minified assets (CSS, JavaScript) from GitHub.
GOV.UK Frontend will allow you to build services that comply with the guidance in the Service Manual.

'Functional' means the components may not look perfect in the given browser, but must still be usable without errors and without 'looking broken'.
If you are including GOV.UK Frontend as part of a stylesheet that you are generating in your application's build pipeline, you will need to generate and include a separate stylesheet in order to support Internet Explorer 8.
GOV.UK Frontend will allow you to build services that comply with the guidance in the Service Manual.
