Spacing between rows…

Hi,

When I make two rows with page builder I have noticed that I get a gap between them. Lets say that I have text in both. Is there an easy way of reducing this distance? If you follow the URL i have made an example. In addition, how can i get the video to span over the whole page (no white gap on each side…)?

I am using Omni theme, page builder and widgets bundle…
