Can I just make a simple form

I would like to make a simple form that is one page, without next, with a plain white background.

The form I'm working on it Contact Us

From the account settings page, disable the new form layout:

This will allow for creating the old style forms which can be single page with basic formatting. 

I have made a demo for you:
