Subheadings are things which give more specific information about what was in the previous "superheading." A subheading can become a superheading by simply adding another subheading below it.
This is a superheading. And a subheading. A that previous sentence was a fragment. Following subheadings can be a good or bad thing. Each new subheading could give more specifics about the previous subheading.
