Rails uses bootstrap

Add ' Bootstrap-sass ' to the Gemfile file and run the bundle install

' Bootstrap-sass '

Add a line of code to the CONFIG/APPLICATION.RB to make Bootstrap-sass and asset pipeline compatible

  classApplication <rails::application#Settings in config/environments/* take precedence over those specified here.    #application configuration should go to files in Config/initializers    #--All. rb files in that directory is automatically loaded.    #Set time.zone default to the specified zone and make Active Record Auto-convert to this zone.    #Run "rake-d time" for a list of the tasks for finding time zone names.

To use bootstrap you also need to create a CSS file in the App/assets/stylesheets directory: custom.css.scss

The contents are:

@import "Bootstrap-sprockets" @import "Bootstrap"

Also add a line to the App/assets/javascripts/application.js file

= Require bootstrap

This enables the use of bootstrap JavaScript components.

Now it's time to start using bootstrap.
