Package Exports

postcss-prefixwrap

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (postcss-prefixwrap) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Getting Started

0. Ensure all Dependencies have been resolved.

1. Install the Node module:

npm install postcss-prefixwrap

2. Load the module in your build configuration:

var prefixwrap = require("postcss-prefixwrap");

3. Instantiate the PostCSS plugin:

// This will be a class on the container div.
var wrapSelector = ".my-custom-wrap";

// Postcss config for some workflow such as webpack.
{
  postcss: [
    prefixwrap(wrapSelector)
  ]
}

4. Add the container to your markup:

<div class="my-custom-wrap">
<!-- Your existing markup. -->
</div>

5. Your css will now be contained:

/* Before */

p {
  color: red;
}

body {
  font-size: 16px;
}

/* After */

.my-custom-wrap p {
  color: red;
}

.my-custom-wrap {
  font-size: 16px;
}
