There is currently no support for preprocessors such as Less, or for sharing variables across CSS files.

CSS preprocessors have become a vital part of build processes.

Let's not sell CSS preprocessors 😉


First, install preprocessor of your choice. Sass seems the most popular weapon of choice at the moment, so we'll use it as an example.

There's no need to point out sass' popularity.

First, install the preprocessor of your choice. For example, with sass:

👍 Also let's not use "weapon" in text.


```
npm install node-sass --save-dev
```

Then in `package.json` just add the following lines to `scripts`, replacing file paths accordingly.
```
...
"scripts": {
...
"build-css": "node-sass src/sass/base.scss src/index.css",
"watch-css": "npm run build-css && node-sass src/sass/base.scss src/index.css -w",
...
}
...
```

> Using a different preprocessor should be just a matter of replacing `build-css` and `watch-css` scripts to something that matches the preprocessor you're using.

"To use a different preprocessor, replace..."


Add these scripts to the main scripts, by pasting `npm run watch-css &` to `start` script and `npm run build-css &&` to `build`.

& won't work as intended on windows (it will wait for the watch process to exit before continuing). One possible solution is |. See http://stackoverflow.com/questions/30950032/how-can-i-run-multiple-npm-scripts-in-parallel

"build-css": "node-sass src/sass/base.scss src/index.css",
"watch-css": "npm run build-css && node-sass src/sass/base.scss src/index.css -w",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
...
```

Finally, you can use `npm start` or `npm run build` as usual.

## Adding Images and Fonts

With Webpack, using static assets like images and fonts works similarly to CSS.
