How to I use custom CSS with Bootstrap 4 and Rails 5

Question

I am using bootstrap 4 and rails 5, I have used render :layout => false so that my main app layout isn't on my login page but I am using Bootstrap to style the login page which works. I have some custom css from the Bootstrap login page example and I don't know where to save it in my rails app, or how to make sure my login page (sessions#new) picks it up. Does anyone know?

Even if you put layout: false , Rails will continue to load the applications.scss. You can create a sass partial (if you're using sass) and import it in the application.scss
