The GOV.UK Design System launched on 22 June 2018
GOV.UK Frontend Toolkit:
- is no longer maintained
- will only be updated for major bug fixes and security patches
- does not meet the Web Content Accessibility Guidelines (WCAG 2.1 level AA) accessibility standard
This framework will remain available in case you’re currently using it. To help your service meet accessibility requirements, you should use the GOV.UK Design System. You can migrate to the Design System from GOV.UK Frontend Toolkit.
GOV.UK frontend toolkit
This project is not tied to a specific language and is designed to be used as a dependency in as many different languages as needed.
Gemfile and a
package.json in this directory, but they are only
for running tests and are not an indication that this project prefers
Ruby or Node.js.
Ruby on Rails
If you are using a build tool that depends on Libsass then you
may need to upgrade to a more recent version to use the grid helpers. Minimal
compatible versions include
gulp-sass 1.2.0 and
The easiest way to integrate it would be to create a
package.json file in your application with
You then install the toolkit with
npm install --save govuk_frontend_toolkit.
If you need stylesheets they will live in (
With Django you can use https://github.com/jrief/django-sass-processor to compile Sass files.
Note: if you need complete styles you might want to install govuk-elements-sass package that also installs toolkit
Using the tagged versions
Each version of the toolkit is tagged with the version number in this format:
v*version number*, for example
v4.1.1 for version 4.1.1.
If your dependency management tool allows the use of Git repositories as dependencies, you can point to a version by using its tag.
For example, if you are using bower, you can add the toolkit to your
bower.json like so:
"govuk_frontend_toolkit": "git://github.com/alphagov/govuk_frontend_toolkit#v4.1.1" (assuming you want version 4.1.1)
Using git submodules
You can include the toolkit as a git submodule.
To add the submodule to your project run the following command substituting the path to a subdirectory in your project's assets directory:
$ git submodule add https://github.com/alphagov/govuk_frontend_toolkit.git ./path/to/assets/govuk_frontend_toolkit
We recommend you use
https rather than
ssh for submodules as they don't require key exchanges when deploying to remote servers.
If you clone a project with the toolkit submodule installed you will need to initialise the submodule with the following command:
$ git submodule init
To update the toolkit to the latest version you can use:
$ git submodule update
to check the stylesheets.
The requirements are Node.js 0.8 or higher and PhantomJS, and Ruby:
bundle install npm install npm test
Using the local test runner
The test suite can be run by opening the
./spec/support/LocalTestRunner.html file in a browser for a more detailed trace of errors.
At the top of a Sass file in your project you should use an
to include the file for the mixins you require, eg if you want the
conditionals and typography mixins you should add:
@import '_conditionals'; @import '_typography';
You may need to include the relative path to the toolkit if it is installed as a submodule:
If you are compiling Sass from the command-line tool, here are some options we recommend.
sass --style expanded --line-numbers --load-path [path to]/govuk_frontend_toolkit/stylesheets input.scss output.css
sass --style compressed --load-path [path to]/govuk_frontend_toolkit/stylesheets input.scss output.css
