+title: Adding a CSS Modules Stylesheet
+---
+
+> Note: this feature is available with `react-scripts@2.0.0` and higher.
+
+This project supports [CSS Modules](https://github.com/css-modules/css-modules) alongside regular stylesheets using the `[name].module.css` file naming convention. CSS Modules allows the scoping of CSS by automatically creating a unique classname of the format `[filename]\_[classname]\_\_[hash]`.
+
+> **Tip:** Should you want to preprocess a stylesheet with Sass then make sure to [follow the installation instructions](#adding-a-sass-stylesheet) and then change the stylesheet file extension as follows: `[name].module.scss` or `[name].module.sass`.
+
+CSS Modules let you use the same CSS class name in different files without worrying about naming clashes. Learn more about CSS Modules [here](https://css-tricks.com/css-modules-part-1-need/).

+### `Button.module.css`
+
+```css
+.error {
+  background-color: red;
+}
+```
+
+### `another-stylesheet.css`
+
+```css
+.error {
+  color: red;
+}
+```
+
+### `Button.js`
+
+```js
+import React, { Component } from 'react';
+import styles from './Button.module.css'; // Import css modules stylesheet as styles
+import './another-stylesheet.css'; // Import regular stylesheet
+
+class Button extends Component {
+  render() {
+    // reference as a js object
+    return <button className={styles.error}>Error Button</button>;
+  }
+}
+```
+
+### Result
+
+No clashes from other `.error` class names
+
+```html
+<!-- This button has red background but not red text -->
+<button class="Button_error_ax7yz"></div>
+```
+
+**This is an optional feature.** Regular `<link>` stylesheets and CSS files are fully supported. CSS Modules are turned on for files ending with the `.module.css` extension.
