Heading hierarchy

In most office publishing software, the style library proposes a specific style for each heading level, generally up to six levels.

The heading hierarchy is consistent when the nesting of heading levels is consistent (the nesting levels of headings reflect how content depends on other content).

Note: the presence of hierarchical jumps (e.g. moving from a level 2 heading to a level 4 heading) does not invalidate the criterion but is not recommended.
