Ruby on Rails 4, stylesheets and pictures

Question

Im learning Ruby on Rails using a book, based on RoR 3, unfortunately, I see that some things are different since the last update of the framework. I really dont understand how to use CSS files, js plugins and include Pictures. I see that there is three different assets folders and I understand that we use them according to what we want to do? Concretely, I'm trying to add a css stylesheet and loading it by the application.html.erb file, to add it to my product page. Thanks for your help.

Answer 1

You should go through the rails asset pipeline documentation, which explains how to place all the assets.

For example Js, Css and Images. Here is the link to it,
