Hi,
Thank you for reaching out to us.
Can you give me more details regarding what are you trying to achieve?
The form design can be customized through CSS. There are two recommended ways:
1. Write CSS that overwrites our Paid Member Subscriptions styling directly in your theme. You can then target just the elements that interest you.
2. Copy the css found inside wp-content\plugins\paid-member-subscriptons\assets\css\style-front-end.css directly in your theme and disable Profile Builder to load it’s own css.
What we don’t recommend is starting from scratch and try to re-do all the CSS. Unless you have a particular need to do it like that, I would recommend the above.
Best regards,
