How to change font size of static text item...?

[hell2heaven]

I am a newbie to gwt...I need to change the font size of static text item.I tried to do it by using the method " setTextBoxStyle("h1") " as below in my "GwtProj.java" file

        StaticTextItem heading=new StaticTextItem();
        heading.setDefaultValue("Enter School Information");
        heading.setTextBoxStyle("h1");

In the above code,"h1" means base css class ...where it looks like below in my "GwtProj.css" file.

h1 {
  font-size: 2em;
  font-weight: bold;
  color: #777777;
  margin: 40px 0px 70px;
  text-align: center;
}

I haven't altered anything in my "GwtProj.gwt.xml" file.should i do any modifications overthere...?

Where did I go wrong in the procedure above...?please help...

I resolved the issue to some extent...I have changed the java file and the css base class in the following way

        StaticTextItem heading=new StaticTextItem();
        heading.setDefaultValue("Enter School Information");
        heading.setTextBoxStyle("heading");

css base class is as follows...

.heading{
	font-size: 2em;
	font-weight: bold;
}

But even after that...I am getting a textbox like thing around my heading " Enter School Information ".It looks like a noneditable textbox.
Can anyone please suggest me,how to get rid of that one...?
