Forms - Formatting

Hello,

I thought I had seen a video that had a snippit about how to format a form to show multiple fields on a single line. For example, when you have a start date and end date, I'd like both those fields to be on a single line instead of one below the other. My form has quite a few fields (even with using logic to only display upon selections), so I'd like it to be a shorter form if possible.

Any guidance would be greatly appreciated!
