# CSS Modules: Extract Imports
[](https://travis-ci.org/css-modules/postcss-modules-extract-imports)
Transforms:
```css
:local(.continueButton) {
composes: button from "library/button.css";
color: green;
}
```
into:
```css
:import("library/button.css") {
button: __tmp_487387465fczSDGHSABb;
}
:local(.continueButton) {
composes: __tmp_487387465fczSDGHSABb;
color: green;
}
```
## Specification
- Only a certain whitelist of properties are inspected. Currently, that whitelist is `['composes']` alone.
- An extend-import has the following format:
```
composes: className [... className] from "path/to/file.css";
```
## Building
```
npm install
npm build
npm test
```
