Heads up! This blog post hasn't been updated in over 2 years. CodePen is an ever changing place, so if this post references features, you're probably better off checking the docs. Get in touch with support if you have further questions.

We had a user write in about this, so I thought I'd explain it in one three-step graphic:

You have to a be a PRO member, because you'll need to apply Custom CSS to a theme. As a PRO, you get unlimited embed themes as well and you'll probably want to make this a special theme in case you don't want to apply it to every single embedded Pen.

  1. Create some CSS that hides that button: #rerun-button { display: none; } You could even use a Pen for this and link directly to the CSS by adding .css to the end of the URL.
  2. Create a new theme in the Embed Builder, and link to that CSS as part of that theme. Remember to choose that theme from the dropdown when embedding a Pen where you want to hide that button.
  3. Now when you see that embedded Pen, that CSS will apply, and the run button will be hidden.
