headingsMap
A very useful tool to help you decide which headings sizes to choose. This is used in Step 2. The extension generates a document-map or index of any web document structured with headings and/or with sections in HTML 5. It shows the headings structure, and the errors in the structure (ie. incorrect levels) that can hurt your website's Accessibility score.
