CSS Minifier

Compresses a CSS string/file with no possible side-effect.

• Removes useless white spaces, indentation characters and line breaks
• Strips all comments
• Removes the last semi-colon of a style declaration and extra semi-colons
• Removes empty CSS declarations
• Removes units when using zero values
• Removes the leading 0 if a float value is lower than one
• Chances RGB color values to a shorter hexadecimal format
• Hexadecimal colors following the pattern #AABBCC are reduced to #ABC
• Keeps a single charset per CSS file removing all extra declarations
• None values are converted to 0 whenever safe to do so
