Form Layout - Sections/ Horizontal space

Form Layout - Sections/ Horizontal space

Hi,

I am trying to improve the layout/alignment of fields on my form and can not see how. Fields just automatically fill down from the top which I guess is OK when using single column but with double column related fields don't always line up.
For example if I add a comment field

Is it possible to add horizontal padding between fields?
      (I thought about adding some extra fields and then hiding them but they are still visible to me as an admin)
