Stylesheets in Tutorial - 404

[Gerald Wodni <gerald wodni gmail com>]

Hi everybody,
I'm a big gtkmm fan, but since a couple of days the css-file of the tutorial 
http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/index.html doesn't 
work anymore :/  would be great if somebody finds the file and moves it back 
to its origin,
tnx
fiz
