New form layout: Custom CSS options

Using the “Single question on One Page” form, is there any way to modify CSS or download the source?

The option does not exist.

We are sorry for the confusion. My colleague is talking about the "All Questions in One Page" layout. We don't have the source code and custom CSS features in "Single Question in One Page" layout. 

You need to create a form with "All Questions in One Page" layout to download the source code of your form. To create a form with "All Questions in One Page" layout, please go to "My Forms" section and click on the "Create Form" button. Finally, make your choice.

Thank you.

Now, do you have any timeline or plans for allowing CSS customization, source download, or any other means of customizing forms using the "Single Question in One Page" layout?

Unfortunately, we have no exact date. This kind requests have been already assigned to our developers. It will be evaluated and if it is implemented you will be informed.

We are currently investigating why our users needs CSS injection on JotForm Cards. As my colleagues has already mentioned, JotForm Cards has no CSS injection feature but if you can tell us which styles and how you want to change with custom CSS, we will try to find a way to meet your requirement. 

Waiting for your valuable returns. 

As we did not hear from your side, we want to send a second notice you regarding your CSS request. We would be pleased if you can tell us why you need this feature, to change which styles and how?

As we can allow our users to open one single thread per question or request, I had to split your second request regarding source code option to the following thread:
