Is there a way to include a static CSS file in GWT similar to how JavaScript files are included?

I am trying to include a static CSS file, app.css, into my application.

When it comes to including JS files, I know how to do it using ScriptInjector like this:

ScriptInjector.fromUrl(pathToJsFile)
    .setWindow(ScriptInjector.TOP_WINDOW)
    .setCallback(new Callback<Void, Exception>() {

        @Override
        public void onFailure(Exception reason) {

        }

        @Override
        public void onSuccess(Void result) {


        }

    })
    .inject();

However, I cannot find an equivalent for CSS files. StyleInjector does not seem to have a method like StyleInjector.fromUrl(...).

Is there a way to add static CSS files to my GWT application?

Edit:

This is how my static CSS file looks like:

* {

}

html {

}


body {

}

Answer №1

To implement an interface like the one below, make sure to include the css file in the same package:

public interface CustomStyles extends ClientBundle {
    public static final CustomStyles INSTANCE = GWT.create(CustomStyles.class);
    @Source("styles.css")
    @CssResource.NotStrict
    CssResource css();
}

In your entry point module or any accessible location, add the following code:

CustomStyles.INSTANCE.css().ensureInjected();
