是否通过变量传递Angular对象属性？

<!-- 组件模板 -->
<div [ngStyle]="myStyles">Hello World</div>

// 组件类
import { Component } from '@angular/core';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponentComponent {
  myStyles = {
    'color': 'red',
    'font-size': '20px'
  };
}
