Thank you very much for your reply, it works nicely with the "invisible" 
item.

I do have in my code objects (GtkColorBar, GtkButtton) for which I 
created css
properties my self to match some specifics using:


void provide_gtk_css (gchar * css)
{
  GtkCssProvider * provider = gtk_css_provider_new ();
  gtk_css_provider_load_from_data (provider, css, -1, NULL);
  gtk_style_context_add_provider_for_screen (gdk_screen_get_default (),
                                             GTK_STYLE_PROVIDER(provider),
                                             GTK_STYLE_PROVIDER_PRIORITY_APPLICATION);
  g_object_unref (provider);
}


About what I understand this is now automatic (somewhat) for many (all 
?) widgets,

Out of curiosity do you think that there is anyway to get that heigh 
value from
a query to the css properties of that menu bar ? is there anyway to send 
query to the css ?


Best
