## Description

The Page Structure Chrome extension provides web developers and accessibility evaluators an intuitive way to assess a web page's structural compliance with accessibility standards like WCAG 2.1 and WAI-ARIA 1.2. By leveraging the Firefox Sidebar, users can view the page title, hierarchical HTML headings, and ARIA landmark regions all at once.

This tool is invaluable for ensuring that screen reader users receive an accurate overview of page content and landmarks, facilitating efficient navigation. Headings and landmarks are clearly presented and can be selected to highlight and scroll to the respective element on the page. This helps authors fine-tune content labeling and structure to enhance accessibility and user experience for people with visual impairments.
