[SOLVED] Increasing the height of root panel in gwt

Increasing the height of root panel in gwt

I have a html panel and i want to add the html panel to browser screen hence i used rootPanel.get().add(htmlPanel);. But their is a extra space between the starting of the screen and the first widget in html panel (As in image). I tried with setting rootPanel.get().setheight("100%") and rootPanel.get().setsize("100%","100%") but it doesn't seem to work please help i want to remove the extra space and so that the widget starts from beginning.

enter image description here

Solution

This padding is added by GWT Bootstrap for its NavBar widget. See the note in the javadoc:

NOTE: We assume that most people will use the ResponsiveNavbar, so, we automatically add a padding-top: 50px in body.If you don't want this, you have to put a padding-top: 0px; manually in your document body tag.
