This app allows you to easily select a linkable ID. Simply copy the full URL, open it in a new tab and it will show you the closest linkable element. The fragment identifier of an URL can be changed directly through the tooltip or by pressing Ctrl+Alt.

A hash fragment of an URL is used to show the element ID, where the numbers and letters are not case-sensitive. This helps you to understand how the HTML is structured.

There are two types of linkable elements: the root element and the most immediate child element. The first of them is what you're used to seeing.
