Ui: s, the style is not displayed

Question

I would like to use CSS to use multiple widgets.

I see that the css class name is confused, but the class definition is not displayed when I check the element in firefox / chrome. Here are my codes. Can anyone suggest that I am missing? Thank you

Style.css

.nameSpan {  color: #3E6D8E; background-color: #E0EAF1;} 

Resources.java

public interface Resources extends ClientBundle { 
  @Source("Style.css") 
  Style style(); 
  public interface Style extends CssResource { 
    String nameSpan(); 
  } 
} 

uibinder.ui.xml

<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' 
    xmlns:g='urn:import:com.google.gwt.user.client.ui'> 
  <ui:with field='res' type='com.my.app.widgets.logoname.Resources'/> 
  <g:HTMLPanel> 
      <div> 
        Well hello there 
        <g:InlineLabel ui:field='nameSpan' styleName="res.style.nameSpan">kevin</g:InlineLabel>
      </div> 
  </g:HTMLPanel> 
</ui:UiBinder> 

uibinder.class

public class uibinder extends Composite { 
        private static uibinderUiBinder uiBinder =     GWT.create(uibinderUiBinder.class); 
        interface uibinderUiBinder extends UiBinder<Widget, uibinder> {} 
        @UiField(provided = true)  final Resources res;  // the style doesn't show no matter provided=true is declared or not. 
        public uibinder(Resources res) { 
                res = GWT.create(Resources.class); 
                initWidget(uiBinder.createAndBindUi(this)); 
        } 

Answer 1

You have to use res.style().ensureInjected()

Answer 2

You need to specify a style attribute ( styleName). For instance:

<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui'> 
    <ui:with field='res' type='com.my.app.widgets.logoname.Resources'/> 
    <g:HTMLPanel> 
        <div> 
            Well hello there 
            <g:InlineLabel ui:field='nameSpan' styleName="{res.nameSpan}">kevin</g:InlineLabel>
        </div> 
    </g:HTMLPanel> 
</ui:UiBinder>
