<h1>$(document).ready Problems in CodePen</h1>
  
<p id="output"><strong>$(document).ready output:&nbsp;&nbsp;</strong></p>
  
<p>The first time I tried to use JQuery's $(document).ready event handler on CodePen, it didn't work for some reason. Other JQuery selectors were working fine, so I thought I'd try this solution, which has worked for me since. The solution was simply <strong>not</strong> to use the quick-add feature of the pen settings page, but instead, to paste the CDN reference (which is fine) into a standard script tag.</p>
<p>Once I did that, $(document).ready worked fine!</p>

  <!-- Add your script tag here, don't auto-include it! -->
