Space between rows

My form here - - is looking a little compacted, is there a way to put a little air between the rows so it looks a little prettier and my visitors don’t feel like they’ve accidentally fallen into a shredder?
Many thanks to someone smarter than me

This CSS will put a little space above the field labels:

body .gform_wrapper label.gfield_label {

That can go into your child theme style sheet, or directly into the Appearance Customizer (Appearance > Customize > Additional CSS).
