Pen Settings

CSS Base

Vendor Prefixing

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.

+ add another resource

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

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 another resource

Use npm 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. We'll also process your JavaScript with Babel.

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

Code Indentation

     

Save Automatically?

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

Auto-Updating Preview

If enabled, the preview panel updates automatically as you code. If disabled, use the "Run" button to update.

* See https://greensock.com/gsap/ for details about GSAP.
* 
* We simply create a TimelineMax and then each part of the 
* animation is modularized into its own function that returns a 
* tween or timeline, which we dump into the main timeline to very
* easily build something much more complex. It also allows us to
* jump around during production to various spots using times or labels
* like when we're tweaking the part that's 30 seconds into the animation, 
* we just add master.seek(30) at the end to have it jump there for preview
* (rather than watching the first 30 seconds every...single...time). 
* This technique also allows us to attach a scrubber to the entire
* thing, speed it up or slow it down, re-order the pieces of the animation, etc.
