Maintain logical heading order

A logical heading structure allows screen reader users to navigate the page content efficiently and helps all users understand the relationship between different sections.

Quick Reference

• Use heading levels (<h1>-<h6>) in sequential order
• Do not skip heading levels (e.g., <h1> followed by <h3>)
• Ensure the document structure is logical and hierarchical

Check

Check the heading structure of the page to ensure that heading levels are not skipped (e.g., check that an <h2> follows an <h1>).

Fix

Adjust the heading levels to ensure a correct hierarchy (e.g., change an <h3> to an <h2> if it follows an <h1>).

Explain

Explain how a consistent heading hierarchy aids navigation for screen reader users who rely on heading lists to understand page layout.

Code Review

Review the rendered markup and interactive states that affect Maintain logical heading order. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
