How to add margin to content without making it shift pages unnecessarily

[santialbo]

I would like to separate non-breakable Views. I've been trying to use margin but I'm facing the following issues:
If I use marginTop, when a View starts a page, there's an unnecessary margin (corresponding to marginTop)
If I use marginBottom, I face the following: If the margin makes the view larger than the space available, then the entire view goes to the next page. (In the image below, the green View shifts to the next page eventhough it would actually fit in the page.

What's is the rigth way of separating non breakable content and avoiding this unnecesary spacing issues?
