How to customize space between Parallax Front Page widgets?

I’m having problems with the customization of my Front Page.
I have a slider and then several Parallax Front Page widgets (please see at, but I would like to customize the spaces between those widgets as they are huge right now…
Please your help or advice.
Many thanks,

Hello there,

I hope you are doing well today.

You do not seem to have the Shapely theme active, could you please activate the theme so that I can inspect the issue?

Best Regards,
