Landing Page quesion Mautic 6.0

I testet the new Landingpage Template “Blend”
Here is a test landingpage:

My question: How can i close the gap between the send button (between the form and the text) and the disclaimer text at the botton?

How to change the size of the page generally? Can’t find the right paramters for it.
Maybe here is one of the devs who makes a tutorial with the basic features.
