title: Jekyll: How to include specific file from collection?
body: <p>I have a collection of css files I combine into one with Jekyll. This is very easy:</p>
  
  <pre><code>{% for file in site.css %}
  {{ file }}
  {% endfor %}
  </code></pre>
  
  <p>However, there is a special case where I want to include just a single one of those files. The <code>pages.css</code> file.</p>
  
  <p><code>site.css</code> is a collection, so I simply put all my css files in a folder called <code>_css</code> and in <code>_config.yml</code> added: </p>
  
  <pre><code>collections:
    css:
      output: false
  </code></pre>
  
  <p>I was able to include only the <code>_css/pages.css</code> files using <code>{{ site.css | where:"title", "Pages" | first }}</code>. But I was wondering if there is a nicer way of doing it. Something like <code>{{ site.css/pages.css }}</code></p>
  
  <p>Is there a way to do it like that? Wihtout a <code>where</code> and <code>first</code> clause?</p>
