Screencasts provided by Railscasts (Ryan Bates)

Twitter Bootstrap Basics in this episode you will learn how to include Twitter Bootstrap into Rails application with the twitter-bootstrap-rails gem.

More on Twitter Bootstrap in this episode continues on the Twitter Bootstrap project showing how to display flash messages, add form validations with SimpleForm, customize layout with variables, and switch to using Sass. (Note: This episode is pro episode)

Installing Gem

Include the Twitter Bootstrap Rails gem in Gemfile to install it from;

gem "twitter-bootstrap-rails"

or you can install from latest build;

gem 'twitter-bootstrap-rails', :git => 'git://'

You can run bundle from command line

bundle install

Installing to App (using Generators)

You can run following generators to get started with Twitter Bootstrap quickly.

Install (requires directives to Asset pipeline.)


rails g bootstrap:install

Layout (generates Twitter Bootstrap compatible layout) - (Haml and Slim supported)


rails g bootstrap:layout [LAYOUT_NAME] [*fixed or fluid]


rails g bootstrap:layout application fixed

Themed (generates Twitter Bootstrap compatible scaffold views.) - (Haml and Slim supported)


rails g bootstrap:themed [RESOURCE_NAME]


rails g scaffold Post title:string description:text
rake db:migrate
rails g bootstrap:themed Posts

Notice the plural usage of the resource to generate bootstrap:themed.

Using with Less

Bootstrap was built with Preboot, an open-source pack of mixins and variables to be used in conjunction with Less, a CSS preprocessor for faster and easier web development.

Using stylesheets with Less

You have to require Bootstrap LESS (bootstrap_and_overrides.css.less) in your application.css

 *= require bootstrap_and_overrides

/* Your stylesheets goes here... */

If you'd like to alter Bootstrap's own variables, or define your LESS styles inheriting Bootstrap's mixins, you can do so inside bootstrap_and_overrides.css.less:

@linkColor: #ff0000;

Using Javascripts

You have to require Bootstrap JS (bootstrap.js) in your application.js

//= require twitter/bootstrap

  /* Your javascripts goes here... */

Using Coffeescript (optionally)

Using Twitter Bootstrap with the CoffeeScript is easy. twitter-bootstrap-rails generates a "" file for you to /app/assets/javascripts/ folder.

jQuery ->

Using Helpers

Flash helper

Add flash helper <%= bootstrap_flash %> to your layout (built-in with layout generator)

Using Static CSS, JS (w/o Less)

twitter-bootstrap-rails has seperate branch (w/o Less) that just serves latest static CSS, JS files.

You can install from latest build (from branch);

gem 'twitter-bootstrap-rails', :git => 'git://',
                               :branch => 'static'
