  • Artikel

The Accessibility tab is where you view the accessibility tree, ARIA attributes, and computed accessibility properties of DOM nodes.

To open the Accessibility tab:

  1. In a rendered webpage, right-click an element and then select Inspect.

    DevTools opens, with the Elements tool selected. The DOM tree opens to show the element that you right-clicked.

  2. In the DOM Tree, click the element that you want to inspect. You can use the arrow keys to move through the DOM tree.

  3. Click the Accessibility tab, to the right of the Styles tab. You might need to first click the More tabs (the More tabs button) button to the right of the Styles tab.
