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.

Babel includes JSX processing.

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.

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.

  ?onlyCryptos=BTC,ETH,NEO  Only display the cryptocurrencies with the tickers you choose
  ?excludeCryptos=TRX,EOS   Exclude cryptocurrencies changing tickers

If you know the wallet address of the user, you can have this address automatically filled by generating iframes with the following argument added:



                html, body, #onramper-widget {
  height: 100%;
