Hi @maxwellB ,
Great question about how to format forms differently for Mobile vs Desktop only!
When it comes to formatting sign up forms for mobile devices, it’s great to take into consideration the user experience as condensing a desktop form could change to form to an unintended design. In this case, it would be best to create a separate sign up form specifically designed for mobile only.

The Desktop & Mobile option you may see in your signup form editor does not create a new mobile form. Instead, it is utilized so that you can choose what blocks appear based on the customer’s viewing device. For this reason, you would want to go into your signup form creation page and create a new form that is designed for mobile. You can either make your own from scratch, or use one of our prebuilt signup forms from the form library!
