Answer 2

One can access CSS classes through GWT code but not its class attributes through setStyleName(String) method. For example

Button button = new Button();
button.setStyleName("Stylename");

for example css of

.StyleName {
 background : #abcdef;
 }

Further you can change the value of some attributes without css like

button.setWidth("100px");
button.setHeight("20px");
