How to make a Jotforms Full Width in the header area?

I am using a Jotforms Embed Script to add to a WordPress Header as this creates a more visualy appealing look to the landing page. How do I edit the Script code to make it full width? Or stretched width?

Is this the form in question? https://www.jotform.com/81366663884167 

Unfortunately, the width of the form cannot be changed in card forms. However, it will adjust to the width of the frame of your page where you have embedded it, so you may try to reduce it. Let us know if you need more help.
