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.
This feature is available from Chrome version 105. In earlier versions, the preview below doesn't work.

badge in the following preview:
In the preview, click Open dialog.
