How To Integrate Drupal And Tailwind CSS: A Step-By-Step Guide

In today’s fast-paced digital world, having a responsive and visually appealing website is crucial. Drupal, known for its robustness and flexibility, is a top choice for content management systems (CMS). On the other hand, Tailwind CSS, with its utility-first approach, offers an efficient way to style websites. Integrating these two can give your website a professional look while maintaining the performance and flexibility that Drupal offers. As a leading Drupal development company, LN Webworks brings you this step-by-step guide to seamlessly integrate Drupal and Tailwind CSS.

Why Tailwind CSS?

Tailwind CSS is different from traditional CSS frameworks. Instead of providing predefined components, it offers low-level utility classes that let you build custom designs without leaving your HTML. This approach leads to more maintainable and less bloated CSS, which is crucial for performance optimization.

Step 1: Setting Up Drupal

Before integrating Tailwind CSS, ensure you have a Drupal environment ready. You can either set up Drupal locally or use a service like Acquia or Pantheon for hosting.

Download and Install Drupal: Visit the official Drupal website and download the latest version. Follow the installation instructions provided to set up your Drupal site.
Create a Custom Theme: In Drupal, themes define the visual aspect of your website. Navigate to the /themes/custom directory and create a new folder for your custom theme, e.g., my_theme.

Step 2: Setting Up Tailwind CSS

With Drupal set up, the next step is to integrate Tailwind CSS into your custom theme.

Install Node.js and npm: Tailwind CSS requires Node.js and npm (Node Package Manager). If you haven't installed them, download and install the latest versions from the official Node.js website.
Initialize npm in Your Theme Folder: Open your terminal, navigate to your theme folder (/themes/custom/my_theme), and run the command:
```
npm init -y
```
This command initializes a new npm project and creates a package.json file.
Install Tailwind CSS: Install Tailwind CSS and its dependencies by running:
```
npm install tailwindcss postcss autoprefixer
```
Create Tailwind Configuration Files: Generate Tailwind and PostCSS configuration files by running:
```
npx tailwindcss init -p
```
This will create a tailwind.config.js and postcss.config.js in your theme folder.

Step 3: Configuring Tailwind CSS

With Tailwind CSS installed, you need to configure it to work with your Drupal theme.

Set Up Tailwind’s Input and Output Files: In your theme folder, create a new folder called src. Inside src, create a styles.css file. Add the following lines to styles.css:
```
@tailwind base;
@tailwind components;
@tailwind utilities;
```
Update package.json Scripts: In package.json, replace the "scripts" section with the following:
```
"scripts": {
  "build": "npx tailwindcss -i ./src/styles.css -o ./css/styles.css --watch"
}
```
This script will compile your Tailwind CSS and output it to a css folder in your theme directory.
Run Tailwind CSS: In your terminal, run:
```
npm run build
```
This command will start Tailwind in watch mode, automatically recompiling your CSS whenever changes are made.

Step 4: Integrating Tailwind CSS With Drupal

Now that Tailwind CSS is set up, you need to integrate it into your Drupal theme.

Link Tailwind CSS in Your Drupal Theme: In your theme’s .info.yml file (e.g., my_theme.info.yml), add the following line to include the generated Tailwind CSS file:
```
stylesheets:
  all:
    - css/styles.css
```
Clear Drupal Cache: To see the changes, clear your Drupal cache by navigating to Configuration > Performance and clicking on "Clear all caches."
Start Designing: With Tailwind CSS successfully integrated, you can start designing your Drupal site using Tailwind’s utility classes.

Step 5: Optimize for Production

When you're ready to deploy your Drupal site, optimize your Tailwind CSS for production to reduce the file size.

Enable PurgeCSS: In tailwind.config.js, configure PurgeCSS to remove unused CSS classes:


module.exports = {
  purge: ['./templates/**/*.html.twig', './src/**/*.js'],
  // Other settings...
}

Rebuild CSS for Production: Run the following command to rebuild your CSS for production:
```
npm run build
```
This will generate a minified CSS file without any unused styles.
