@astrojs/tailwind

This Astro integration brings Tailwind’s utility CSS classes to every .astro file and framework component in your project, along with support for the Tailwind configuration file.

Tailwind lets you use utility classes instead of writing CSS. These utility classes are mostly one-to-one with a certain CSS property setting: for example, adding the text-lg to an element is equivalent to setting font-size: 1.125rem in CSS. You might find it easier to write and maintain your styles using these predefined utility classes!

If you don’t like those predefined settings, you can customize the Tailwind configuration file to your project’s design requirements. For example, if the “large text” in your design is actually 2rem, you can change the lg fontSize setting to 2rem.

Tailwind is also a great choice to add styles to React, Preact, or Solid components, which don’t support a <style> tag in the component file.

Note: it’s generally discouraged to use both Tailwind and another styling method (e.g. Styled Components) in the same file.

The astro add command-line tool automates the installation for you. Run one of the following commands in a new terminal window. (If you aren’t sure which package manager you’re using, run the first command.) Then, follow the prompts, and type “y” in the terminal (meaning “yes”) for each one.

# Using NPM
npx astro add tailwind
# Using Yarn
yarn astro add tailwind
# Using PNPM
pnpm astro add tailwind

If you run into any issues, feel free to report them to us on GitHub and try the manual installation steps below.

First, install the @astrojs/tailwind and tailwindcss packages using your package manager. If you’re using npm or aren’t sure, run this in the terminal:

npm install @astrojs/tailwind tailwindcss

Then, apply this integration to your astro.config.* file using the integrations property:

import { defineConfig } from 'astro/config';
import tailwind from '@astrojs/tailwind';

export default defineConfig({
  // ...
  integrations: [tailwind()],
});

When you install the integration, Tailwind’s utility classes should be ready to go right away. Head to the Tailwind docs to learn how to use Tailwind, and if you see a utility class you want to try, add it to any HTML element to your project!

If you used the Quick Install instructions and said yes to each prompt, you’ll see a tailwind.config.cjs file in your project’s root directory. Use this file for your Tailwind configuration changes. You can learn how to customize Tailwind using this file in the Tailwind docs.

If it isn’t there, you add your own tailwind.config.(js|cjs|mjs) file to the root directory and the integration will use its configurations. This can be great if you already have Tailwind configured in another project and want to bring those settings over to this one.

The Astro Tailwind integration handles the communication between Astro and Tailwind and it has its own options. Change these in the astro.config.mjs file (not the Tailwind configuration file) which is where your project’s integration settings live.

If you want to use a different Tailwind configuration file instead of the default tailwind.config.(js|cjs|mjs), specify that file’s location using this integration’s config.path option. If config.path is relative, it will be resolved relative to the root.

import tailwind from '@astrojs/tailwind';

export default {
  integrations: [tailwind({
    // Example: Provide a custom path to a Tailwind config file
    config: { path: './custom-config.cjs' },
  })],
}

By default, the integration imports a basic base.css file on every page of your project. This basic CSS file includes the three main @tailwind directives:

/* The integration's default injected base.css file */
@tailwind base;
@tailwind components;
@tailwind utilities;

To disable this default behavior, set config.applyBaseStyles to false. This can be useful if you need to define your own base.css file (to include a @layer directive, for example). This can also be useful if you do not want base.css to be imported on every page of your project.

export default {
  integrations: [tailwind({
    // Example: Disable injecting a basic `base.css` import on every page.
    // Useful if you need to define and/or import your own custom `base.css`.
    config: { applyBaseStyles: false },
  })],
}

You can now import your own base.css as a local stylesheet.

• The Astro Tailwind Starter gets you up and running with a base for your project that uses Tailwind for styling
• Astro’s homepage uses Tailwind. Check out its Tailwind configuration file or an example component
• The Astro Ink, Sarissa Blog, and Creek themes use Tailwind for styling
• Browse Astro Tailwind projects on GitHub for more examples!

When using the @apply directive in an Astro, Vue, Svelte, or another component integration’s <style> tag, it may generate errors about your custom Tailwind class not existing and cause your build to fail.

error The text-special class does not exist. If text-special is a custom class, make sure it is defined within a @layer directive.

Instead of using @layer directives in a global stylesheet, define your custom styles by adding a plugin to your Tailwind config to fix it:

module.exports = {
  // ...
  plugins: [
    function ({ addComponents, theme }) {
      addComponents({
        '.btn': {
          padding: theme('spacing.4'),
          margin: 'auto'
        }
      })
    }
  ]
}

Certain Tailwind classes with modifiers rely on combining classes across multiple elements. For example, group-hover:text-gray compiles to .group:hover .text-gray. When this is used with the @apply directive in Astro <style> tags, the compiled styles are removed from the build output because they do not match any markup in the .astro file. The same issue may also happen in framework components that support scoped styles like Vue and Svelte.

To fix this, you can use inline classes instead:

<p class="text-black group-hover:text-gray">Astro</p>

• If your installation doesn’t seem to be working, try restarting the dev server.
• If you edit and save a file and don’t see your site update accordingly, try refreshing the page.
• If refreshing the page doesn’t update your preview, or if a new installation doesn’t seem to be working, then restart the dev server.
