What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I'm not really sure what you meant, could you please provide us more information about this?
JotForm form's CSS and JS files are hosts in our servers. If you insert your own custom CSS code using the form builder, then it will stay in our end.
We recommend using the generated script and iframe embed codes in our end so that changes made on the form using the form builder will easily reflect in the live form.
I hope that helps.
