One HTML file, and Multiple CSS files in Rails how?

Question

I have one HTML file located in app/views/layouts/application.html.erb

I use <%=yield=> to render the HTML code from other models. The problem is that I don't know how to distinguish the CSS code. I have a universal CSS code, but each html file needs a different one.

here is my CSS line in app/views/layouts/application.html.erb

<%= stylesheet_link_tag "scaffold" %>
<%= stylesheet_link_tag "welcome_screen/my_CSS.css", :media => "all" %>

put a named yield in the head of the layout file, then use content_for in your specific view

# application.html.erb
<head>
    <%= stylesheet_link_tag "scaffold" %>
    <%= yield(:head) %>
    # ...
</head>
<body>
    <%= yield %>
    # ...
</body>

then your view code

# welcome_screen.html.erb
<% content_for(:head) do %>
    <%= stylesheet_link_tag "welcome_screen/my_CSS.css", :media => "all" %>  
<% end %>

You can add <%= yield :head %> in the <head> tag in application.html.erb. Later in you views if you need some css file

<% content_for :head do %>
  <%= stylesheet_link_tag "some_uniq.css" %>
<% end %>

You can read this for better understaning of how yield command works.
