@Component
struct Index {
  build() {
    Row() {
      RelativeContainer() {
        Row().width(100).height(100)
          .backgroundColor("#FF3333")
          .alignRules({
            left: {anchor: "guideline1", align: HorizontalAlign.End},
            top: {anchor: "guideline2", align: VerticalAlign.Top}
          })
          .id("row1")
      }
      .width(300).height(300)
      .margin({left: 50})
      .border({width:2, color: "#6699FF"})
      .guideLine([{id:"guideline1", direction: Axis.Vertical, position:{start:200}},
        {id:"guideline2", direction: Axis.Horizontal, position:{start:200}}])
    }
    .height('100%')
  }
}
