我希望div使用css从角度2向右滑入.

  <div class="note" [ngClass]="{'transition':show}" *ngIf="show">
    <p> Notes</p>
  </div>
  <button class="btn btn-default" (click)="toggle(show)">Toggle</button>

如果我只使用[ngClass]切换类并使用不透明度,我工作正常.但是李不希望从一开始就渲染这个元素,所以我首先用ngIf"隐藏"它,但是转换不会起作用.

.transition{
  -webkit-transition: opacity 1000ms ease-in-out,margin-left 500ms ease-in-out;
  -moz-transition: opacity 1000ms ease-in-out,margin-left 500ms ease-in-out;
  -ms-transition: opacity 1000ms ease-in-out,margin-left 500ms ease-in-out ;
  -o-transition: opacity 1000ms ease-in-out,margin-left 500ms ease-in-out;
  transition: opacity 1000ms ease-in-out,margin-left 500ms ease-in-out;
  margin-left: 1500px;
  width: 200px;
  opacity: 0;
}

.transition{
  opacity: 100;
  margin-left: 0;
}
