Our current focus
Standard CSS transforms
We're trying to bring every reasonable CSS Spec into all the browsers.
First we keep track of new features through the CSSDB (see the repo). Then we do our best to create a PostCSS plugin that can convert that new syntax/function/rules so every browser can understand it.
While it's not always possible we're enabling over 50 features with these plugins!
Developer experience
We want it to be easier for you to be effective at writing CSS.
From time to time we will publish plugins that aren't related to a standard CSS spec but that we think will help developers.
