Changing multiple form styles

My client is considering using JotForm to host many various forms.  It is critical that the styles of the form match their site's look and feel.  For this, they plan to use custom CSS.

However, they also will be updating their site's look-and-feel later this year.  Is it possible to change the style of multiple JotForms at the same time using custom or external CSS files?

You would need to update the CSS code in each form's CSS area: https://www.jotform.com/help/75-Customize-Your-Form-Using-Custom-CSS-Codes

Unless you find a way to work with the full source code of the forms, where you would remove any Inline or Internal CSS, in order to point to your own External CSS file. You might need to hire a CSS developer to accomplish such a thing.

Let us know if you have more questions, we will be glad to assist you.
