@shelaghm 1) how big should the gap be between the last input widget of the previous question and the question title of the next question 2) if there's subtext to a question title, how big should the gap be between the question title and the subtext, and the subtext and the input widget below the subtext?

@santosh-pingle these things determine if you should implement the gap on the question title, or on the subtext, or the input widget. beacuse if there's no question title, for example, or no subtext, you still want things to look uniform.

This mockup should help answer the question.
