How can I make the fields in my form responsive to screen size?

Hi! I am working on a form that has several questions. I'd like to make my fields and text boxes responsive to the size of the screen on which they are being viewed...or at least, I'd like to make them semi-responsive to browser window size. Is there a way to do this rather than having to select the exact pixel width?

Thanks,

You can enable mobile responsiveness for the form:

This will changes the layout of the form automatically when the devices screen is under a certain pixel width.
