CSS::Tiny is a perl class to read and write .css stylesheets with as little code as possible, reducing load time and memory overhead. CSS.pm requires about 2.6M of memory to load, which is a large amount of overhead if you only want to do trivial things. . This module is primarily for reading and writing simple files, and anything we write shouldn't need to have documentation/comments. If you need something with more power, move up to CSS.pm.
