      public interface Resources extends ClientBundle {
        public static final Resources INSTANCE = GWT.create(Resources.class);
        public interface Style extends CssResource {
        @ClientBundle.Source("resource/myapp.css") // relative path to the css file.
        @CssResource.NotStrict // No compile error if no css class in the css file.
        Style css();

    • package com.myapp.client;
      public class MyApp implements EntryPoint {
        public void onModuleLoadSafe() {
          // Inject the css
          // ... ... ...
