Popup box on the website

A popup box, also known as a modal window or dialog box, is a graphical user interface element that appears on top of a webpage. It usually contains information or a call-to-action that requires the user’s attention, such as a newsletter subscription form, a login prompt, or a message confirming an action.

Popups can be triggered by various events, such as clicking on a button, leaving a website, scrolling to a certain point on the page, or after a set amount of time. They can be useful for providing additional information or prompting the user to take a specific action, but they can also be intrusive if overused or poorly designed.
