Does Gravity Forms Styler play well with Upfront?

Based on your tutorials and my client's needs I've purchased a business license for Gravity Forms; however, I'm rusty in writing CSS so I'm having a devil of a time in getting a fairly simple form to layout properly on my contact page on their development site - blackmothersunited.wsbydesign.com. I just came across Gravity Forms Styler created by Code Canyon (see http://codecanyon.net/item/gravity-forms-styler/6817645) and it looks like the answer to my prayers, but before I purchase it I want to make sure that it will work properly with Spirit/Upfront. Can you provide me with an answer and provide directions on how to best use it within Upfront? I appreciate your help!

Sincerely,
Kimberly
