Introduction to <dialog>tag

The <dialog>tag in HTML is a versatile element introduced in HTML5, designed to create interactive dialog boxes and modal windows on web pages. This element provides a structured and semantic way to display content such as alerts, confirmation messages, forms, and more, which require user interaction before continuing with the main page content.
