title: styling each line inside pre with css
body: <p>i have html code</p>
  
  <pre><code>&lt;pre&gt;
  line 1
  line 2
  line 3
  &lt;/pre&gt;
  </code></pre>
  
  <p>how can i put some css style to the "lines" inside <code>&lt;pre&gt;</code>, without adding other wrapper into it?</p>
  
  <p>what i mean is something like</p>
  
  <pre><code>pre lines{ color: red}
  </code></pre>
  
  <p>i'm having difficulties on finding the css selector for that. Thanks in advance.</p>
