It includes stuff like dialogue boxes that open on a screen in reply to a user’s actions, chatbots that react to the user’s distinct behaviour with the equivalent messages. The animation that occurs when a user moves beyond an assured point of a page: any dynamic website function that wants to appear on the screen without the user having to reload a particular site physically.
