First Subscription Option is Too Large?

First Subscription option is making a large white space on our form

I'm afraid that that particular space cannot be adjusted since card forms cannot be modified with CSS, the only what you could do is adjusting the height of the embedded form, which will affect all cards so it might not look properly for the rest of the form.

If you have any further questions, please let us know.

Thank you!

It should look like this:

But please test your form afterward and if you're able to submit it properly.

Let us know if you face any problems.

Thank you!
