GOV.UK Frontend Toolkit

A gem wrapper around the govuk_frontend_toolkit.

Installing

Just include govuk_frontend_toolkit in your Gemfile. It automatically attaches itself to your asset path so the static/SCSS files will be available to the asset pipeline.

You will need to check that the gem is included while in development. Often asset related gems are in a bundler group called assets. Old Rails projects do not inluded this in development by default so you need to ensure bundler is included using the following lines at the top of the /config/application.rb:

if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  Bundler.require *Rails.groups(assets: %w(development test))
  # If you want your assets lazily compiled in production, use this line
  # Bundler.require(:default, :assets, Rails.env)
end

You will also need to ensure that the correct assets are precompiled for production. These are set using the variable config.assets.precompile in /config/application.rb. An example of what this may look like is:

config.assets.precompile += %w(
  application.css
  application-ie8.css
  application-ie7.css
  application-ie6.css
  application.js
)

Usage

At the top of a Sass file in your Rails project you should use an @import rule to include the file for the mixins you require. For example if you want the conditionals and typography mixins you should add:

@import '_conditionals';
@import '_typography';
