The function that typically displays a pop-up window in web development is alert(), used in JavaScript. When called, it creates a modal dialog box with a specified message and an "OK" button for the user to dismiss it. Other functions, such as confirm() and prompt(), also create pop-up windows but serve different purposes, allowing for user input or confirmation.
Use the window.open() function. Remember that visitors generally hate popups. Don't use the winow.open() function. You can also use: alert("place the message in a popup box here")
A popup is a window or advertisement that appears on your screen while browsing the internet. This tends to happen more in Internet Explorer. Popups can be rid of by installing a Popup Blocker.
System Alert is a popup window generated when any of the configured activity occurs.

To make a popup on WordPress responsive, ensure that you use a plugin that supports responsive design, such as Popup Maker or Elementor. Customize the popup's CSS by using media queries to adjust its size and layout based on the screen size. Additionally, check the plugin settings for options related to mobile responsiveness and test the popup on different devices to ensure it displays correctly. Finally, consider using percentage-based widths rather than fixed pixel sizes for better adaptability.
