body: <p>I want to include a file inside the <code>&lt;head&gt;</code> section. 
  (the file conatains all the css, and js file that should be included in every page in the site)</p>
  
  <p>It is done easily with PHP, 
  I'm trying to do this in angular and it doesn't work. </p>

  <pre><code>&lt;div ng-include="'/Partials/header.html'"&gt;&lt;/div&gt;
  </code></pre>
