Tidify Build Status

Tidify is a fast and simple formatter for CSS and SCSS code.

Tidify can format following code:

  • Vanilla CSS
  • SCSS syntax of Sass

and Tidify is 3 to 4 times faster than Stylefmt.

Tidify'd code is:

  • easier to write : never worry about minor formatting concerns while hacking away.
  • easier to read : when all code looks the same you need not mentally convert others' formatting style into something you can understand.
  • easier to maintain : mechanical changes to the source don't cause unrelated changes to the file's formatting; diffs show only the real changes.
  • uncontroversial : never have a debate about spacing or brace position ever again!

$ npm install tidify

$ yarn add --dev tidify
