Online CSS minifier

Reduce your website weight and increase your pages speed !
Minification (also minimisation or minimization), in computer programming languages and especially JavaScript, is the process of removing all unnecessary characters from source code without changing its functionality. These unnecessary characters usually include white space characters, new line characters, comments, and sometimes block delimiters, which are used to add readability to the code but are not required for it to execute.
Minified source code is especially useful for interpreted languages deployed and transmitted on the Internet (such as JavaScript), because it reduces the amount of data that needs to be transferred. Minified source code may also be used as a kind of obfuscation, though the term obfuscation may be distinguished as a form of false cryptography while a minified code instance may be reversed using a pretty-printer. (source wikipedia)
Scripts are in pure javascript to prevent generated minified CSS storing which could be seen by server administrator.
