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?

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
We recommend using the latest version of Chrome, Edge, Firefox, or Safari. The page supports dark, light and other website themes, and adjusts the fields and results layout for mobile, tablet and desktop widths.
