Top layer

This badge helps you understand the concept of the top layer and visualize it. The top layer renders content on top of all other layers, regardless of z-index. When you open a <dialog> element using the .showModal() method, the browser puts it into the top layer.

To help you visualize top layer elements, the Elements panel adds a #top-layer container to the DOM tree after the closing </html> tag.

Top layer elements have top-layer (N) badges next to them, where N is the element's index number. The badges are links to the corresponding elements in the #top-layer container.

Discover the top-layer (N) badge in the following preview:

  1. In the preview, click Open dialog.
  2. Inspect the dialog.
  3. In the DOM tree, click the top-layer (1) badge next to the <dialog> element. The Elements panel takes you to the corresponding element in the #top-layer container after the closing </html> tag. The top-layer container and badge.
  4. Get back to the <dialog> element by clicking the reveal badge next to the element or its ::backdrop.
