This is a CSS autoprefixing module for the Mimosa build tool. It will transform your CSS code to have the necessary/configured vendor prefixes.

For more information regarding autoprefixer, see https://github.com/ai/autoprefixer.

For more information regarding Mimosa, see http://mimosa.io.


Add 'autoprefixer' to your list of modules. That's all! Mimosa will install the module for you when you start mimosa watch or mimosa build.


Autoprefixer lets you write your CSS rules without needing to consider vendor prefixes.

This module will run autoprefixer over your CSS during mimosa watch and mimosa build. It will rewrite the CSS to include the selected vendor prefixes. It will create a source map for the altered CSS. If the incoming CSS had an inline source map, autoprefixer will rebuild that map.

Default Config

autoprefixer: {
  browsers:[ "> 1%", "last 2 versions", "Firefox ESR", "Opera 12.1" ],
  map: true,
  cascade: true
  • browsers: list of browsers to use, see the info on browsers on the autoprefixer github. The default here is the autoprefixer default.
  • map: whether or not to create inline maps, maps and source are always inlined
  • cascade: make output look like this
a {
    -webkit-box-sizing: border-box;
       -moz-box-sizing: border-box;
            box-sizing: border-box
