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.

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.

      <td colspan="3">Started this as I was seeing what appeared to be broken CSS Variables... but turned out to be a misunderstanding on how calc is implemented in browsers.  Some properties allow you to take any unitless number and multiply it by a number+unit to get a final unit value... others do not.  As of Firefox 57, everything in this test works except the colors. Safari and Chrome support all of the ones I've tested. Edge does fine with px, vmin, and other linear distance units... but does not seem to handle degrees, unitless,&nbsp;etc. (except in colors, interestingly)</td>
