Creating a simple fade in/out animation

AngularJS animations work by integrating CSS animations into a directive class-based finite state machine. In other words, elements in AngularJS that serve to manipulate the DOM have defined class states that can be used to take full advantage of CSS animations, and the system moves between these states on well-defined events. This recipe will demonstrate how to make use of the directive finite state machine in order to create a simple fade in/out animation.

Note

A finite state machine (FSM) is a computational system model defined by the states and transition conditions between them. The system can only exist in one state at any given time, and the system changes state when triggered by certain events. In ...
