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
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

sass --style compressed --load-path [path to]/govuk_frontend_toolkit/stylesheets input.scss output.css
