This is a great tool for tidying up your CSS and removing deprecated, unknown vendor pseudo-elements, unknown pseudo-classes and unknown vendor extended pseudo-elements – it will also remove invalid tags, compress down tags such as changing “0px” to “0” and many other alterations to give you the most slimline and hack-free CSS file, because lets face it… the internet has moved on and we no longer need those horrible vendor specific classes or those IE hacks.
Just paste your CSS in the input window below, all the best settings are checked by default, turn features on and off if you have some issues or preferences and then click “clean my css”… IT’S AS EASY AS THAT!
Note: Keep a backup of the original just in case.
