   */
  readonly FULL_HEIGHT_PERCENT: string = '100%';

  build() {
    Row() {
      Column() {
        Text(this.TITLE)
          .fontSize(14)
          .fontColor(0xFEFEFE)
          .fontWeight(600)
        Text(this.CONTEXT)
          .fontSize(14)
          .fontColor(0xFEFEFE)
          .fontWeight(600)
      }
      .width(this.FULL_WIDTH_PERCENT)
    }
    .backgroundImage($r("app.media.new_bg"))
    .backgroundImageSize(ImageSize.Cover)
    .height(this.FULL_HEIGHT_PERCENT)
    .onClick(() => {
      postCardAction(this, {
        "action": this.ACTION_TYPE,
        "abilityName": this.ABILITY_NAME,
