        use dreamer. when do this experiment, we can directly use dreamweaver。note that we must first insert a layout
         object/ div label.ID写drag,紧接着点击底下的“新建css样式”，高级ID，#drag，仅对该文档。
          then must have 定位，类型，绝对， position:absolute;
         上面这一步同样可以在html网页中， 任何时候点击右键：css样式/新建， 达到同样效果。
         after finish the wizard, we can also change the css property by right-clicking the #drag in the right window.
         then editing it.
