Why does my form not always fit on the form builder?

As I have used JotForm over the past year or more. I have noticed that my forms and fields don't always fit or match up to the form builder screen. What can i do to fix this?

Some forms really do not fit on the Form Builder view. There are other CSS code that are being loaded in the Form Builder like the tools CSS that causes the issue. And also the width set to the form is larger or wider than the Form Builder so it will overflow with the Form Builder. To ensure that the design are properly rendered in your form, please Preview the form and open it in a new tab (or you can access the direct link of the form).

Do let us know if you need further assistance.
