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.

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.

Add Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import or require. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

If active, Pens will autosave every 30 seconds after being saved once.
