title: How to use `reveal-code-focus` within `org-mode` in Emacs?
body: <p>I would like to use <code>reveal-code-focus</code> within <code>org-mode</code> in Emacs (<a href="https://bnjmnt4n.github.io/reveal-code-focus/#/reveal-code-focus" rel="nofollow noreferrer">https://bnjmnt4n.github.io/reveal-code-focus/#/reveal-code-focus</a>). Is there an example that someone could walk me through on how to do it? I have looked and looked but not found any help.</p>
  
  <pre><code>#+BEGIN_SRC python :results output
     import random
     random.seed(1)
     print("Hello World! Here's a random number: %f" % random.random()) 
  #+END_SRC
  </code></pre>
  
  <p>In the above example I want the background color for random.seed(1) to be highlighted when exporting to HTML using reveal.js.</p>
  
  <p>Please note that, it is not for syntax highlighting but for code focus.</p>
