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.

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.

Save Automatically?

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

 * Stylus Cache Function
 *
 * This is a demo of the cache function included
 * with Stylus.
 *
 * Try making $useCache false. You'll see that
 * by default, Stylus outputs all properties created
 * by the `funkyText` mixin each time it's used.
 *
 * 1. The `maybeCache` function is for demo purposes
 *    only. It's a wrapper for Stylus' cache function
 *    that allows us to easily switch caching on
 *    or off.
 *
 * 2. If caching is enabled, we call Stylus' cache
 *    mixin with the passed arguments.
 *
 * 3. Cache is a "block" mixin; meaning it receives
 *    and can use Stylus blocks.
 *
 * 4. We use a static cache key here because
 *    the font is the same every time the mixin is
 *    called. It should always be cached.
 *
 * 5. `$colour` and `$size` can change each time the
 *    mixin is called. We create a cache key for each
 *    (prefixed with the mixin name to avoid conflicts).
 *    Whenever the key matches an existing item, Stylus
 *    extends, rather than duplicates, the matching block.

🕑 One or more of the npm packages you are using needs to be built. You're the first person to ever need it! We're building it right now and your preview will start updating again when it's ready.
