CSS for block properties

I’ve been experimenting with the DB version, and am getting my head around how tags now work.

While the new properties for blocks (are they now called nodes?) are great, visually they bleed into the content of the block itself.

For example, in this block I would like the text properties (which I have highlighted in a red box) to be distinct from the first sub-bullet regarding the call from Fred.

Can anyone let me know what CSS customisation keys I need to use in order to make these properties distinct from block sub-bullets (whether by adding colour to the text of the properties and their values, or creating a panel or box for the properties and their values)?

Alternatively, is this something where I should just sit tight because it will be addressed as part of the DB development?

Many thanks.
