removing white spaces betweem rows

I am rebuilding my site with the pagebuilder and each time I fill a page the space between rows gets bigger…. Can you help? Also a 3/4 with 1/4 row does not display as one row on iPad and mobile. You will have to log in to see what I mean since this is a copied closed site… I can send you screenprints if you like
