What causes an animation in angular path transitions?
Angular is confused because we haven’t defined the trigger yet! So let’s do it now. Remember, an animation is caused by a trigger that causes a transition from one state to another state. When we define an animation, we start with the trigger and work our way down into that definition.

What do you need to know about animation in angular?
The state is a static style definition. A transition defines how a property in the style will change. A trigger defines what action will cause a state to transition to another state. “animation” = Triggered transition(s) from one state to another. To connect animations to the router we need to add a data property to the route configuration.
How to define transition from one state to another in angular?
Angular uses a simple arrow syntax to define the transition from one state to another. For example, if we want to handle navigation from One to Two, we use One => Two. If we want to handle both directions, we can use a bidirectional arrow, One <=> Two, and then the transition going from One to Two and Two to One will be applied.
How do you animate a container in angular?
Styling the views animates the containers in place, without the DOM moving things around. Apply this to the style definition by adding the following: First, style ( { position: ‘relative’ }) sets the style on the element that is the target of the trigger to be position: relative.
When do you use void in a transition in angular?
You can use the void state to set transitions for an element entering or exiting a page. You can combine wildcard and void states in a transition to trigger animations that move in and out of the page: a transition of * => void is applied when the element leaves a view, regardless of what state it was in before leaving.
How are transition states defined in angular?
In Angular, transition states can be defined explicitly via the state() function, or by using the default * (wildcard) and void states. An asterisk * or wildcard matches any animation state.
