A {@link Rule} can be compared to a CSS media query and it's content. In CSS media queries you define a condition anda block that will be active when this query becomes active. With a {@link Rule} it's the same. You define{@link Condition}s and instead of a block you will define {@link Instruction}s.

A {@link Rule} is used everywhere in Passe-Partout. You work with them when using {@link FluidGridLayout}, {@link QueryListener} or responsive {@link Resource}s.
