How can I have more control over the styling of the <iframe> element used for Hosted Tokenization?

Hi all,

We have been exploring the option of using HT for our payment system in a web app. We are plugging the <iframe> into our HTML and assigning CSS to it through parameters in the URL.

We would like the <iframe> element used in Hosted Tokenization to treat "Helvetica" as a valid font-family, and to adjust the order of the elements so the labels would appear underneath the input fields, so that we can have consistency in the look and feel of our web app.

Is it possible for us to do either of those things?
