I should have mentioned that whitespace is considered to be any of the following characters:
0x09 - horizontal tab
0x0a - linefeed
0x0b - vertical tab
0x0c - form feed
0x0d - carriage return
0x20 - space
so keep that in mind when you program for trimming whitespace...

css::minifier
CSS::Minifier(3pm) User Contributed Perl Documentation CSS::Minifier(3pm)
NAME
CSS::Minifier - Perl extension for minifying CSS
SYNOPSIS
To minify a CSS file and have the output written directly to another file
use CSS::Minifier qw(minify);
open(INFILE, 'myStylesheet.css') or die;
open(OUTFILE, 'myStylesheet.css') or die;
minify(input => *INFILE, outfile => *OUTFILE);
close(INFILE);
close(OUTFILE);
To minify a CSS string literal. Note that by omitting the outfile parameter a the minified code is returned as a string.
my minifiedCSS = minify(input => 'div {font-family: serif;}');
To include a copyright comment at the top of the minified code.
minify(input => 'div {font-family: serif;}', copyright => 'BSD License');
The "input" parameter is manditory. The "output" and "copyright" parameters are optional and can be used in any combination.
DESCRIPTION
This module removes unnecessary whitespace from CSS. The primary requirement developing this module is to not break working stylesheets: if
working CSS is in input then working CSS is output. The Mac/Internet Explorer comment hack will be minimized but not stripped and so will
continue to function.
This module understands space, horizontal tab, new line, carriage return, and form feed characters to be whitespace. Any other characters
that may be considered whitespace are not minimized. These other characters include paragraph separator and vertical tab.
For static CSS files, it is recommended that you minify during the build stage of web deployment. If you minify on-the-fly then it might be
a good idea to cache the minified file. Minifying static files on-the-fly repeatedly is wasteful.
EXPORT
None by default.
Exportable on demand: minifiy()
