The Government Digital Service (GDS) is retiring GOV.UK Frontend Toolkit following the launch of the GOV.UK Design System. GOV.UK Frontend Toolkit will remain available to you if you are currently using it but will no longer be maintained. GDS will only roll out major bug fixes and security patches.
For new projects, you can get all of the information about GOV.UK styles, components and patterns in the GOV.UK Design System.
A collection of Sass and JavaScript files for using as part of your application's frontend.
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.
There's a 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.
We recommend you use the govuk_frontend_toolkit_gem and follow the installation instructions.
govuk_frontend_toolkit_npm is an NPM package that can be installed or included in your package.json.
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 node-sass 1.0.0, grunt-sass 0.16.0,
gulp-sass 1.2.0 and libsass 3.0.0.
Requirement: NodeJS installed. This gives you Node Package Manager(NPM) which is required to install npm packages.
The easiest way to integrate it would be to create a package.json file in your application with npm init
You then install the toolkit with npm install --save govuk_frontend_toolkit.
If you need javascript files, they will live in (node_modules/govuk_frontend_toolkit/javascripts).
If you need stylesheets they will live in (node_modules/govuk_frontend_toolkit/stylesheets).
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
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)
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
Tests for this project use Jasmine for the JavaScript and Ruby's scss and scss-lint
to check the stylesheets.
The requirements are Node.js 0.8 or higher and PhantomJS, and Ruby:
bundle install
npm install
npm testgovuk_frontend_toolkit uses standardjs, an opinionated JavaScript linter.
All JavaScript files follow its conventions. Read more
The test suite can be run by opening the ./spec/support/LocalTestRunner.html file in a browser for a more detailed trace of errors.
The files for unit tests and any supporting JavaScript should be added to ./spec/manifest.js file.
At the top of a Sass file in your project you should use an @import rule
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:
@import '../toolkit/_conditionals';
If you are compiling Sass from the command-line tool, here are some options we recommend.
In development:
sass --style expanded --line-numbers --load-path [path to]/govuk_frontend_toolkit/stylesheets input.scss output.css
In production:
sass --style compressed --load-path [path to]/govuk_frontend_toolkit/stylesheets input.scss output.css
