How to write the slide open page in angular2?

In the

site, click to the right to display one page and to the left to display another page. I really don"t know how to write the class file in the hero component, and the big god can help.

Code in the animation class file:

import {animate, state, style, transition, trigger} from"@ angular/animations";

class AnimationAnimateMetadata {
}

export const slideInDownAnimation: AnimationAnimateMetadata =
trigger ("routeAnimation", [

)
state("*",
  style({
    opacity: 1,
    transform: "translateX(0)"
  })
),
transition(":enter", [
  style({
    opacity: 0,
    transform: "translateX(-100%)"
  }),
  animate("0.2s ease-in")
]),
transition(":leave", [
  animate("0.5s ease-out", style({
    opacity: 0,
    transform: "translateY(100%)"
  }))
])

]);

The code in the

hero component template:
< div [@ routeAnimation] = "routeAnimation" class= "my-5" >

Hello!


Hello!


Hello!


Hello!


Hello!


Hello!


Hello!


Hello!


Hello!


< / div >

Code in the hero component class file:
import {Component, OnInit, HostBinding} from"@ angular/core";

@ Component ({
selector: "app-hero",
templateUrl:". / hero.component.html",
styleUrls: [". / hero.component.css"],
})

export class HeroComponent implements OnInit {
@ HostBinding ("@ routeAnimation") routeAnimation = true;
@ HostBinding ("style.display") display =" block";
@ HostBinding ("style.position") position =" absolute";
constructor () {
}

ngOnInit () {
}
}
