I found out about some cool tools this week:
CSS Optimizer via David Chartier
CSS Optimizer is a simple command line application that optimizes files used for web-development, such as external CSS files. It reduces the filesize significantly, 20-60% depending on your coding style, by stripping unneeded characters such as whitespace, tabs, newline characters, and semi-colons; but, it only elimates ones that are not vital to proper display of the CSS file. CSS Optimizer also converts long-hand CSS declerations to short hand equivilents to eliminate even more unneeded characters. CSS Optimizer has been tested to work under many browsers such as Firefox, Mozilla, Safari, and IE; currently I have not found a browser that it does not work successfully on.
