What is the HTML Landmark Landmark Mirror?

Check the number, name and nest relationship of Header, Nav, Main, Aside, Footer and ARIA Roll. ToolHub places the core operation in the browser, so that the desktop and the action device can be used immediately, without registration of account numbers or the need to send the content back to the back.

How to use this tool?

  1. Enter the data according to the field prompts and select the required processing method.
  2. Click "Process Now" to view the results, indicator summary and necessary error messages.
  3. After confirming that the content meets actual needs, you can copy the results or download them into files for further use.

Suitable use cases

All the work is done in the current page break, especially for workflows that do not want to post in-house information to a remote service.

Interpretation of results and precautions

Automatic checks only identify structural problems, and complete accessibility still requires keyboard and screen-reading. Tools validate basic input formats and provide readable error messages, but the formal environment should be reconfirmed according to source specifications, business rules or professional requirements.

Browser and device support

HTML Landmark Auditor supports current Chrome, Edge, Firefox, and Safari releases. Mobile and desktop layouts use the same validation rules documented on this page.
