Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

JavaScript

Babel is required to process package imports. If you need a different preprocessor remove all packages first.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

  <p>It’s a good idea to keep your line-lengths at around <code>60-75ch</code> wide to make the content as readable as possible. Here’s some lipsum. It all depends on how large your font is and how easy it reads, but sticking to that sort of range will only ever be good for your readers. Here’s some lipsum.</p>
