jetpack compatability (Generate Pro)

Hi, I would like to purchase Generate Pro from Studio Press, but since I am currently using Jetpack for my subscriptions, the support there is not sure whether I will get the same look of the main enwes opt-in box as on their demo site (the link below).

https://demo.studiopress.com/generate/?color=blue

I am capable of absolutely basic css (changing colors and fonts) only. Could you advice me on the amount of css (if any) required to achieve this demo look…? Also where do I get the form action code…?

Thank you for your help!
