Hi @Shelli Godfrey ,
Thanks for the post.
Unlike the header and the footer, body configuration only allows defining one or more sections and adding one or more columns into each of those sections.
The body part of the form does not support setting the style with JSON.
It is recommended that you use PowerApps.
For more information you could refer to this article: Configure custom body with one or more sections
I hope I can offer you a better experience next time if I have a chance to work with you again.
Yours faithfully,
Renjie Sun
