Heading level skipped
What it means
These pages jump down more than one heading level at once, such as an <h2> straight to an <h4>. Screen reader users navigate by heading, and a gap reads as a missing section.
How to fix it
Use heading levels to describe structure, not size: go down one level at a time and style them with CSS. Jumping back *up* any number of levels is fine: that is just a new section. WCAG 1.3.1.
