At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed.

You can reset your form's styling by using this theme from our store: http://www.jotform.com/theme-store/theme/default-theme.
However, if you want to do a full reset (this means it will also remove your custom CSS code) then you can do the following:
1. Open "Preferences"->Form Styles->Set "Themes" to "Default" and delete all the code under the "Inject Custom CSS".
2. After that, save the changes and use this theme: http://www.jotform.com/theme-store/theme/default-theme
I hope that helps.
Thank you Charlie! this did help :-)
