1. Inside style blocks it's pretty much regular CSS except for interpolation and if/case expressions, so you can create a style for the root element and then use ids and classes if you desire, but it won't be optimized.

2. CSS definitions without interpolation compile down to static CSS while the ones with interpolation compile down to CSS variables which are set on the element where the style is assigned. This also allows for passig arguments to styles [0].

CSS nesting is supported and the interpolation doesn't conflict with the id selectors because interpolation is not supported in selectors.
