title: How to inject content of CSS file into HTML in Gulp?
body: <p>I need to insert the content of a stylesheet into the <code>&lt;head&gt;</code> of an HTML page. How can I do it in Gulp?</p>
  
  <p>Before (what I have):</p>
  
  <pre><code>&lt;head&gt;
    &lt;link href="style.css" rel="stylesheet" type="text/css" /&gt;
  &lt;/head&gt;
  </code></pre>
  
  <p>After (what I want):</p>
  
  <pre><code>&lt;head&gt;
    &lt;style&gt;
       p { color: pink; }
    &lt;/style&gt;
  &lt;/head&gt;
  </code></pre>
  
  <p>Note that I do not need to inline CSS into the elements, but just put the contents of CSS in the <code>&lt;head&gt;</code>.</p>
