Use tomorrow's CSS syntax, today.

cssnext is a CSS transpiler that allows you to use the latest CSS syntax today. It transforms CSS specs into more compatible CSS so you don’t need to wait for browser support.

If you're using PostCSS in your build process, and want to add cssnext, you need only postcss-cssnext (check the "options" section here below). Otherwise, if you like cssnext to work as a full standalone package with its own cli (independently of PostCSS), use cssnext.

cssnext was at first designed to be a complete tool, before PostCSS became popular; thus, includes some options that don't really belong in a PostCSS plugin (e.g., import, url, compress, plugins). These days, most people use PostCSS directly so we decided to make integration of cssnext more simple by providing a simple (real) plugin.

If you were using cssnext with some options here is what you need to know:

• import: just add into your plugins list postcss-import
• url: just add into your plugins list postcss-url
• compress: just add into your plugins list cssnano
• plugins: just add the plugins directly in your list
• messages: see postcss-reporter and postcss-browser-reporter
• sourcemap, map, to, from: see PostCSS source map documentation

We plan to offer a simple migration by making postcss better. Please track this issue #208
