常规写法

@Entry
@Component
struct FancyUse {
  @State label: string = 'Hello World'

  build() {
    Row({ space: 10 }) {
      Text(`${this.label}`)
        .fontStyle(FontStyle.Italic)
        .fontWeight(100)
        .backgroundColor(Color.Blue)
      Text(`${this.label}`)
        .fontStyle(FontStyle.Italic)
        .fontWeight(200)
        .backgroundColor(Color.Pink)
      Text(`${this.label}`)
        .fontStyle(FontStyle.Italic)
        .fontWeight(300)
        .backgroundColor(Color.Orange)
    }.margin('20%')
  }
}
