/*
Customize RailsAdmin theme here.
Copy this file to your app/assets/stylesheets/rails_admin/custom/theming.scss, leave this one untouched
Don't require it in your application.rb
Look at the markup in RailsAdmin and go there to get inspiration from:
http://getbootstrap.com
Test me: (actual color should be the one defined in variables.scss if you did)
body { background-color: $link-color; }
