 In Angular, you can set multiple styles without any animation. However, without further refinement, the button instantly transforms with no fade, no shrinkage, or other visible indicator that a change is occurring.
 
-To make the change less abrupt, we need to define an animation *transition* to specify the changes that occur between one state and another over a period of time. The `transition()` function accepts two arguments: the first argument accepts an expression that defines the direction between two transition states, and the second argument accepts an `animate()` function.

The `transition()` function accepts two arguments: the first argument accepts an expression that defines the direction between two transition states, and the second argument accepts one or a series of `animate()` functions.
 
 
 Use the `animate()` function to define the length, delay, and easing of a transition, and to designate the style function for defining styles while transitions are taking place. You can also use the `animate()` function to define the `keyframes()` function for multi-step animations. These definitions are placed in the second argument of the `animate()` function.
