Foundation for Rails


Gem Version

Foundation::Rails is a gem that makes it super easy to use Foundation in your upcoming Rails project.


Add this line to your application's Gemfile:

gem 'foundation-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install foundation-rails

Configuring Foundation

You can run the following command to add Foundation:

$ rails g foundation:install

Generating Haml or Slim versions of the markup can be done by appending the --haml or --slim option to the above command.

Motion UI

Motion UI is a Sass library for creating flexible UI transitions and animations, and it comes packaged with the foundation-rails gem. To use Motion UI, uncomment the following lines from foundation_and_overrides.scss:

// @import 'motion-ui/motion-ui';
// @include motion-ui-transitions;
// @include motion-ui-animations;

Manual Installation

Add Foundation to your CSS

Append the following line to your app/assets/stylesheets/application.css file:

/*= require foundation

If you're planning on using Sass, then you'll want to rename application.css to application.scss. That file should then look like:

@import "foundation_and_overrides";
/* Add imports of custom sass/scss files here */

Add Foundation to your JS

Append the following lines to your app/assets/javascripts/application.js file:

//= require foundation

Set Viewport Width

Add the following line to the head of your page layout:

<meta name="viewport" content="width=device-width, initial-scale=1.0" />


Run the generator to add foundation to the asset pipeline:

rails g foundation:install [layout_name] [options]

  [--haml]  # Generate HAML layout instead of erb
  [--slim]  # Generate Slim layout instead of erb
Runtime options:
  -f, [--force]    # Overwrite files that already exist
  -p, [--pretend]  # Run but do not make any changes
  -q, [--quiet]    # Suppress status output
  -s, [--skip]     # Skip files that already exist
