Sections

A section is a subdivision of a chapter separated from other sections with a break. It usually indicates a new twist in the story — changes in time, location, point-of-view character, mood, tone, emotion, and/or pace.^[1] Sections have an extra space between them to improve readability since they do not always have titles or order numbers.

However, if you place a section under a heading, make sure it has a lower rank than the heading of a document (<h1>) and the subheadings of chapters (<h2>).
