# Tailwind CSS with Emotion.js example

This is an example of how you can add [tailwind CSS](https://tailwindcss.com/) with [Emotion.js](https://emotion.sh/docs/introduction) in your web app. It takes inspiration from [examples/with-tailwindcss](https://github.com/vercel/next.js/blob/canary/examples/with-tailwindcss/README.md).

`@tailwindcssinjs/macro` is used to add tailwind classes inside Emotion by injecting the tailwind CSS into the styled component. No need to use CSS files, autoprefix, minifier, etc. You will get the full benefits of Emotion.

## Deploy your own

Deploy the example using [Vercel](https://vercel.com):

## How to use

### Using `create-next-app`

Execute [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init) or [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) to bootstrap the example:

```bash
npm init next-app --example with-tailwindcss-emotion with-tailwindcss-emotion-app
# or
yarn create next-app --example with-tailwindcss-emotion with-tailwindcss-emotion-app
```

### Download manually

Download the example:

```bash
curl https://codeload.github.com/vercel/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-tailwindcss-emotion
cd with-tailwindcss-emotion
```

Install it and run:

```bash
npm install
npm run dev
# or
yarn
yarn dev
```

Deploy it to the cloud with [Vercel](https://vercel.com/import?filter=next.js&utm_source=github&utm_medium=readme&utm_campaign=next-example) ([Documentation](https://nextjs.org/docs/deployment)).

## Notes

The CSS classes generated by Emotion will include the tailwind styles but not the name of the classes. For example the following component:

```jsx
const Header = styled.div`
  ${tw`font-mono text-sm text-gray-800`}
`
```

Will be transformed into:

```css
.css-25og8s-Header {
  font-family: Menlo, Monaco, Consolas, 'Liberation Mono', 'Courier New',
    monospace;
  font-size: 0.875rem;
  color: #2d3748;
}
```

### tailwind CSS config

Use the following command when you add a tailwind plugin that adds to tailwind's base css:

```bash
npm run build:base-css
# or
yarn run build:base-css
```
