css-mode.el missing in Emacs v22.1.1

In order to get css-mode working on Emacs v22.1.1, you can download the latest version of:

ftp://mirrors.kernel.org/gnu/emacs/emacs-23.2.tar.gz

Unpackage the .tar.gz file and extract the liisp/textmodes/css-mode.el. Copy it to your ~/.emacs.d directory:

Add this line to your .emacs file:
(autoload 'css-mode "css-mode")

We're assuming the load-path gets added:

(add-to-list 'load-path "~/.emacs.d")
