我想要一个div从右边滑入角2使用CSS。
<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]来切换类和使用不透明度，我就能正常工作。但是li不想从一开始就呈现该元素，所以我首先用ngIf“隐藏”它，但是之后的过渡就不起作用了。
.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;
}

export class App {
show:boolean = false;
}
原件
*ngif在表达式变为false时从DOM中删除元素。不能对不存在的元素进行转换。
改用hidden:
<div class="note" [ngClass]="{'transition':show}" [hidden]="!show">
