title: How is $styles array populated in Opencart?
body: <p>I am beginning to use Opencart and I am making my own template by copying the default template.</p>
  
  <p>When I was going through template/common/header.tpl, I see the following lines</p>
  
  <pre><code>&lt;?php foreach ($styles as $style) { ?&gt;
  &lt;link rel="&lt;?php echo $style['rel']; ?&gt;" type="text/css" href="&lt;?php echo $style['href']; ?&gt;" media="&lt;?php echo $style['media']; ?&gt;" /&gt;
  &lt;?php } ?&gt;
  </code></pre>
  
  <p>I have been thinking for a while, how it is getting populated. Though I have changed the theme to be used as my new theme, it is still populated with old default stylesheets. I will be really thankful if anyone can point me to the direction I have missed. I am sorry if it is a naive question.</p>
