Diagnoses

Here is how tools diagnose the heading level skipped issue for HTML element 278 of the LibreOffice page.

1. Heading levels should only increase by one; Heading order invalid

   Tool: Axe (Deque)

   Rule: heading-order

2. <p>Headings and subheadings create a <a href="https://www.w3.org/WAI/tutorials/page-structure/headings/" target="_blank" title="Opens in new tab">navigable table of contents</a> for assistive devices. The numbers indicate indents in a nesting relationship:</p> <ul> <li>Heading level 1 <ul> <li>Heading level 2: a topic <ul><li>Heading level 3: a subtopic</li></ul></li> <li>Heading level 2: a new topic</li> </ul> </li> </ul> <p>This heading skipped from level 3 to level 5. From a screen reader, this sounds like content is missing.</p> <p><strong>To fix:</strong> adjust levels to form an accurate outline, without gaps.</p>
