title: ReadmoreJS - CodePen does not output anything
body: <p>I was reading upon <a href="https://jedfoster.com/Readmore.js/" rel="nofollow noreferrer">ReadmoreJS</a> and I was thrilled to give it a try on CodePen. However, when I read the instructions on the website and implemented some code on CodePen, it doesn't work at all. Here is a link to my <a href="https://codepen.io/NeroSonic/pen/pGpObO" rel="nofollow noreferrer">CodePen</a> to view the code. In the JS tab, I made sure to include <em>jQuery</em> as the first script and <em>ReadmoreJS</em> as a dependency.</p>
  
  <p>Here is some code snippets from my CodePen:</p>
  
  <blockquote>
    <p>HTML</p>
  </blockquote>
  
  <pre><code>&lt;article&gt;Lorem ipsum and all that jazz...&lt;/article&gt;
  </code></pre>
  
  <blockquote>
    <p>Javascript</p>
  </blockquote>
  
  <pre><code>$('article').readmore();
  </code></pre>
  
  <p>As you can see, I'm targeting every <code>article</code> tag, but it doesn't seem to be working. There are also no console errors. Does anyone know what I might be missing?</p>
