How to apply common nodes style to the list item node?

[nickschinestzki]

I'm trying to use CSS to make the list item markers (1, 2, 3 or a bullet in unordered lists) to follow the style of its content.

Here's an example of how it is right now:

The markers are the same regardless of the font size and color of its content (plus font-weight, etc).
So, how can I apply styles to a whole list item when selecting the full ListItemNode?
