I'm interested in the sky blue contact us form but I don't see how to access the code for it.

Please let me know how to access the code for the sky blue with clouds contact us form.  

Could you please share us the theme/template you want to use? 

I found this one that seems like the one you are describing: https://www.jotform.com/theme-store/theme/partly-cloudy-skies 

That's a template, please follow this guide in order to use it: https://www.jotform.com/help/106-How-to-use-the-form-templates 

A template does not require a form to be previously created, you would be basically cloning the template. 

A theme would require to have a form previously created, this guide will help you applying a theme: https://www.jotform.com/help/184-How-to-Apply-a-Theme-to-Your-Form 

Hope this helps.
