Am I able to edit the CSS / Design of buttons within the Stripe Subscription Widget?

I noticed there aren't any options or a CSS editor for the new "scrollable/multi-part" forms.  Once aspect of these I'd like to adjust is the styling of the buy/subscribe buttons generated through the Stripe widget.

Right now they seem to be uneditable.  Is there a way to inject CSS in that section of the form within the Jotform site or do I need to more or less host the form completely on my site (vs. using an embed) and see if I can edit the CSS there.

Thanks, 

We would like to apologize. I'm afraid the feature you are looking for isn't available with the JotForm Cards. Full Source Codes is also not available with JotForm Cards.

We can submit a feature request, on your behalf, to include a way to inject custom CSS codes to JotForm Cards. However, we cannot guarantee that it will be implemented soon.

You can use the "All Questions in One Page" layout which is more flexible when it comes to styling the form using custom CSS codes.
