title: Joomla! Unset CSS in template index.php
body: <p>I have a custom Joomla 3 template where I use</p>
  
  <pre><code>unset($this-&gt;_scripts[JURI::root(true).'/media/jui/js/bootstrap.min.js']);
  </code></pre>
  
  <p>to unset boootstrap functionality. It works fine for me. Now I want to use same technique to unset a css file and set another one for it.</p>
  
  <pre><code>unset($this-&gt;_scripts[JURI::root(true).'/media/system/css/calendar-jos.css']);
  </code></pre>
  
  <p>And it gives me no result.</p>
  
  <p>How can I solve this issue?</p>
  
  <p>Thanks.</p>
