title: One HTML file, and Multiple CSS files in Rails how?
body: <p>I have one HTML file located in <code>app/views/layouts/application.html.erb</code></p>
  
  <p>I use <code>&lt;%=yield=&gt;</code> 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.</p>
  
  <p>here is my CSS line in  <code>app/views/layouts/application.html.erb</code></p>
  
  <pre><code>&lt;%= stylesheet_link_tag "scaffold" %&gt;
  &lt;%= stylesheet_link_tag "welcome_screen/my_CSS.css", :media =&gt; "all" %&gt;
  </code></pre>
