Re: if change css, need restart the server?

Documentation is really bad for CSS resource - don't think there is even any CSS code in the documentation itself...

Css file my.css would be placed in the same folder as 'MyResources.java' file

If my.css looks like the following:

.className {
 width:100px;
}

.something {
 width: 200px;
}

then MyCss interface must look like this:

interface MyCss extends CssResource {
  String className();
  String something();
}

Now in your actual code, where you have addStyleName("something") before, it must now be addStyleName(resources.css().something())

GWT will now create the minimum css for that style and inject it in.

For more information, we found if using jetty server and development, changing css will reflect in browser in development mode, if using externaml sever, then even using development, changing css will not cause browse UI change.

I have a look about cssResources at
https://developers.google.com/web-toolkit/doc/latest/DevGuideClientBundle#CssResourceCookbook
but feel very complicated, any simpler tutorial to teach about using it?

in its documentation,

Obfuscated CSS class names

CssResource will use method names as CSS class names to obfuscate at runtime.

interface MyCss extends CssResource {
  String className();
}

interface MyResources extends ClientBundle {
  @Source("my.css")
  MyCss css();
}

All instances of a selector with .className will be replaced with an obfuscated symbol when the CSS is compiled. To use the obfuscated name:

MyResources resources = GWT.create(MyResources.class);
Label l = new Label("Some text");
l.addStyleName(resources.css().className());

in a normal css file, there should be many class name, so how to insert the classname in addStyleName()?
