Stripe popup form

Hello everyone!
I am new here in the community and new with the yiiframework.

I just made my first web site with this framework, and all it’s ok. There is just one thing that i need to do. I would like to customize stripe (the style only), it was already implemented but it is a popup. popup|375x500 .

In the past i have already customized stripe, but i had elements inside the page (so was easy), but know i don’t know how to do. I read the documentations, but i found nothing.

Thank you for any help :slight_smile:
