Heading/Typography Spacing

Hi there,

I am learning my way through customizing the look of the body of a page with the editor, it's going pretty well, I figured out pretty much everything I need to in order to now produce the content I need.

My question has to do with padding/spacing between different blocks. Is there an easy way to customize this, block by block? For example, if you scroll down a bit in the URL I provided, you'll see my Google Ratings section. I would perhaps like to lower the spacing between the "heading" and the "paragraph", test and tweak it until I have a look that I feel is right. It does not seem like there is a way.

Thank you
