Hi Jonathan and thank you for your answer!
I know we can create each element separately instead of using the card element but I wanted to avoid that, as I find the card element more easy and more complete. I saw that when using elements seperately I would have to remake a lot of stuff that is automatic with the card element, such as the credit card brand display and the validations.
I was hoping there was a way to "hack" a little bit the card element display in order to split it visually but not in the way it works
