A prompt dialog is often used if you want the user to input a value.
When a prompt dialog pops up, the user will have to click either "OK" or "Cancel" to proceed after entering an input value.
All of AlertifyJS animation/transition effects are disabled due to user preference that the system minimizes the amount of animation or motion it uses. See prefers-reduced-motionCSS media feature.
