What is the HTML element?

The HTML element is a native HTML tag for creating modal or non-modal dialog boxes without any JavaScript library. It supports automatic focus management, keyboard interaction (Esc to close), and native modal behavior.

What's the difference between modal and non-modal dialogs?

A modal dialog prevents interaction with the rest of the page until closed (using showModal()). A non-modal dialog allows interaction with both the dialog and the page (using show()).
