[CLOSED] Undesired top/left margin around viewport with borderlayoutcontainer

I used the following code snippet and I cannot get rid of the unwanted margin on the left and top of the viewport

Code:

---

public class MySampleApplication implements EntryPoint, IsWidget  {

    public void onModuleLoad() {
        Viewport viewport = new Viewport();
        viewport.setWidget(this);
        RootPanel.get().add(viewport);
    }


    public Widget asWidget() {


          final BorderLayoutContainer con = new BorderLayoutContainer();
          con.setBorders(true);
          con.setLayoutData(new MarginData(0, 0, 0, 0));


          return con;
      }
}

---

it shows up as (tried it in chrome and ie9) :

Am I overlooking something here?

This looks like you are not loading the reset.css file.

Thanks Sven for responding (on a sunday ;))
You were right, the path to my 'reset.css' had a typo, all is fine now
