# Next.js + Tailwind CSS Example
|
||||
|
||||
This example shows how to use [Tailwind CSS](https://tailwindcss.com/) (v2.1) with Next.js. It follows the steps outlined in the official [Tailwind docs](https://tailwindcss.com/docs/guides/nextjs).
|
||||
|
||||
It uses the new [`Just-in-Time Mode`](https://tailwindcss.com/docs/just-in-time-mode) for Tailwind CSS.
|
||||
|
||||
## Deploy your own
|
||||
|
||||
Deploy the example using [Vercel](https://vercel.com?utm_source=github&utm_medium=readme&utm_campaign=next-example):
|
||||
|
||||
[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/git/external?repository-url=https://github.com/vercel/next.js/tree/canary/examples/with-tailwindcss&project-name=with-tailwindcss&repository-name=with-tailwindcss)
|
||||
|
||||
## How to use
|
||||
|
||||
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
|
||||
npx create-next-app --example with-tailwindcss with-tailwindcss-app
|
||||
# or
|
||||
yarn create next-app --example with-tailwindcss with-tailwindcss-app
|
||||
```
|
||||
|
||||
Deploy it to the cloud with [Vercel](https://vercel.com/new?utm_source=github&utm_medium=readme&utm_campaign=next-example) ([Documentation](https://nextjs.org/docs/deployment)).
