Customizing CSS for Each Web Page in Rails Application

Exploring the possibility of testing out two different interfaces for my Rails application has led me to consider using two separate CSS files - one for each interface. For instance, I envision having a new_interface.css and an old_interface.css file for this purpose. Currently, I have created two distinct partials for the interfaces: _new_interface.html.erb and _old_interface.html.erb. The challenge now is how to ensure that the correct CSS file is invoked when a specific view is loaded. Essentially, if I were to load _new_interface.html.erb, I want it to utilize the new_interface.css file exclusively, bypassing the old_interface.css file.

Here is a snippet from my application.css:

/*
*= require_tree
*/

This question is focused on how to utilize Rails 3.1 assets pipeline for selectively using specific CSS files. The key is to reorganize the app/assets/stylesheet folder into subdirectories and adjust manifest files to prevent everything from being bundled together at runtime.

By incorporating conditional logic in your view, you can ensure that the appropriate CSS is loaded for each task. Utilizing the content_for tag will be beneficial in this scenario. For instance, you could modify app/views/layouts/application.html.erb by adding a line after other JavaScript code like <%= yield :view_specific_css %>. Then, in your view file, you can include:

<% content_for :view_specific_css do %>
    <%= stylesheet_link_tag "whatever %>
<% end %>

To streamline your CSS management, it's recommended to consolidate both old and new layout styles within the application.css file. Here's how you can achieve this:

In your application.html.haml/erb file, add the following code snippet:

body{:class => @old_layout ? "old_layout" : "new_layout"}

Now, whenever you are in a controller action that uses the old layout, simply include the line:

@old_layout = true

In your CSS files, differentiate between old and new layouts by either prefixing selectors with body.old_layout or body.new_layout, or utilize SCSS for a more organized approach. To implement SCSS, wrap your existing CSS rules like so:

body.old_layout{
  #include all CSS for the old layout here (excluding body declarations)
}

body.new_layout{
  #include all CSS for the new layout here (excluding body declarations)
}

This method not only simplifies your CSS structure into one file but also provides a convenient way to transition each controller action seamlessly.
