Clean CSS, CSS Formatter and Optimizer
Clean CSS is a web-based based on CSSTidy 1.1allowing to format and optimize stylesheets with many options and generating clean css file. There is some interesting notes concerning cleaning CSS is that the same selectors and properties are automatically merged, and your code should be well-formed. Clean CSS is not a validator which points out errors in your CSS code, even that I would prefer an all-in-one tool better than jumping from a tool to another.
