Install Tailwind CSS with SvelteKit - Tailwind CSS 中文网

Create your project
Start by creating a new SvelteKit project if you don't have one set up already. The most common approach is outlined in the Getting Started with SvelteKit introduction.
Terminal
```
npm create svelte@latest my-projectcd my-project
```
Install Tailwind CSS
Install tailwindcss and its peer dependencies, then generate your tailwind.config.js and postcss.config.js files.
Terminal
```
npm install -D tailwindcss postcss autoprefixernpx tailwindcss init -p
```

Enable use of PostCSS in <style> blocks

In your svelte.config.js file, import vitePreprocess to enable processing <style> blocks as PostCSS.

svelte.config.js

import adapter from '@sveltejs/adapter-auto';
import { vitePreprocess } from '@sveltejs/vite-plugin-svelte';
/** @type {import('@sveltejs/kit').Config} */
const config = {
  kit: {
    adapter: adapter()
  },
  preprocess: vitePreprocess()
};
export default config;

Configure your template paths

Add the paths to all of your template files in your tailwind.config.js file.

tailwind.config.js

/** @type {import('tailwindcss').Config} */
export default {
  content: ['./src/**/*.{html,js,svelte,ts}'],
  theme: {
    extend: {}
  },
  plugins: []
};

Add the Tailwind directives to your CSS
Create a ./src/app.css file and add the @tailwind directives for each of Tailwind’s layers.
app.css
```
@tailwind base;
@tailwind components;
@tailwind utilities;
```
Import the CSS file
Create a ./src/routes/+layout.svelte file and import the newly-created app.css file.
+layout.svelte
```
<script>
  import "../app.css";
</script>

<slot />
```
Start your build process
Run your build process with npm run dev.
Terminal
```
npm run dev
```
Start using Tailwind in your project
Start using Tailwind’s utility classes to style your content, making sure to set lang="postcss" for any <style> blocks that need to be processed by Tailwind.
+page.svelte
```
<h1 class="text-3xl font-bold underline">
  Hello world!
</h1>

<style lang="postcss">
  :global(html) {
    background-color: theme(colors.gray.100);
  }
</style>
```
