        width: 5px;
      }

      .resize-handle-left {
        left: 0;
      }

      .resize-handle-right {
        right: 0;
      }
    `,
  ],
  template: `
    <div
      class="rectangle"
      mwlResizable
      [enableGhostResize]="true"
      (resizeEnd)="onResizeEnd($event)"
    >
      <div
        class="resize-handle-top"
        mwlResizeHandle
        [resizeEdges]="{ top: true }"
      ></div>
      <div
        class="resize-handle-left"
        mwlResizeHandle
        [resizeEdges]="{ left: true }"
      ></div>
      <div

        mwlResizeHandle
        [resizeEdges]="{ right: true }"
