Minimize space between widgets on Sidney pro

Hello, I use sidney pro to build a site that is not yet online (local). I have a problem: I have too much space lost between each widget used on the same page. I can not find how to reduce this unnecessary space and that lengthens my pages unnecessarily. I am French and masters your language badly. Could you tell me what to do, where to go to reduce this space in my pages; SIMPLY?
Thank you in advance. Greetings. C. Sébert
Ps: I looked carefully before writing, but everything is too confusing and does not give an accurate solution to my problem. I use the theme absolutely without modification.

Hello Christian,

Each row has 100px top/bottom padding by default. You can remove it in Layout section of row settings.

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
