Stripe: How to change the layout of the payment section?

3 - Also is there any way I can make some changes to the STRIPE payment area - the type alignment is a bit confusing and I again I can't seem to change the active background colour in the design editor.

Could you please specify a bit more the changes that you want to do on your payment integration?

It's currently being displayed like this:

Do you want to move the price box?

Do you want to move the products text? 

With the active background color, do you refer to the active background of your questions or the products in your payment section? 

The background when your questions are active can be easily changed injecting this CSS code:

.form-line.form-line-active{

background:#FFFFFF;

}

Replace the background color with the color that you want.
