Pleeease is a CSS postprocessor. The main goal of this tool is to perform all treatments that a pre-processor shouldn’t have to do! (eg, dealing with prefixes, convert rem to px, support older browsers, etc.).
Pleeease is also a great tool if you want to write DRY, future-proof CSS. For now, it adds prefixes, variables, pseudo-elements and rem unit support, packs same media-query in one @media rule, inline @import styles and minify the result.
Pleeease is based on PostCSS. It helps combine multiple processors and parse CSS only once.
