Modal window

Modal windows are pop-up windows that come up on your computer or phone screen, and you have to do something in them before you can go back to what you were doing before. Imagine playing with your toys and then your mom interrupts and tells you it's time to go to bed. You can't go back to playing with your toys until you listen to your mom and go to bed first. This is sort of how a modal window works. You can't go back to your task until you're done with what the pop-up window is asking you to do. It's a way for websites and apps to get your attention and make sure you do something important or follow a specific process.
