This document has a background color and text (foreground) color for the body. Those colors will be used for any text that is not covered by a more specific rule. This is a paragraph, so it is covered by the rule for paragraphs.
It also has rules for the highest level heading (h1), paragraphs (p), and emphasis (em). It does not have a rule for h2, so second level headings will use the body rule. This is a paragraph, so it is covered by the rule for paragrpahs.
