  }

  animation: prefixed-loader 1.2s 500ms infinite ease-in-out both;
}

.animation-2 {
  animation-name: prefixed-loader;
}

Usage

Step 1: Install plugin:

npm install --save-dev postcss postcss-prefix-keyframe

Step 2: Check you project for existed PostCSS config: postcss.config.js in the project root, "postcss" section in package.json or postcss in bundle config.

If you do not use PostCSS, add it according to official docs and set this plugin in settings.

Step 3: Add the plugin to plugins list:

Better to put above autoprefixer. Also, be aware, if you are using outdated version of autoprefixer, prefixed rules, like -webkit-keyframes wont be processed. In this case, you just need to update autoprefixer version.

module.exports = {
  plugins: [
+   require('postcss-prefix-keyframe')({ prefix: 'prefix-' }}),
    require('autoprefixer')
  ]
}

Options

• prefix String - appends to the beginning of the at-rule and animation name
