# Imagine that your application requires a layout that differs slightly from your regular application layout to support one particular controller
# The solution is nested layout!
#inside your different layout controller add:
layout 'custom'
# app/views/layouts/custom.html.erb
<% content_for :stylesheets do %>
<%= stylesheet_link_tag "custom" %>
<% end %>
<% content_for :content do %>
<%= yield %>
<% end %>
<%= render "layouts/application" %>
# app/views/layouts/application.html.erb
My Application
<%= stylesheet_link_tag "layout" %>
<%= content_for?(:content) ? yield(:content) : yield %>
