What is use PurgeCSS in a Tailwind CSS Project ?

PurgeCSS in a Tailwind CSS project is a tool used to eliminate unused CSS styles from your final production build. It analyzes your codebase and removes any styles that are not applied in your HTML or JavaScript, resulting in a smaller and more optimized stylesheet for better performance.

npm i -D @fullhuman/postcss-purgecss

Step 2: Add the PurgeCSS plugin to the PostCSS configuration:

const purgecss = require('@fullhuman/postcss-purgecss')
module.exports = {
  plugins: [
    purgecss({
      content: ['./**/*.html']
    })
  ]
}

• Reduced File Size: PurgeCSS significantly reduces the size of your CSS file by removing styles that are not utilized in your project, resulting in faster page loading times.
• Improved Performance: Smaller stylesheets lead to quicker downloads, reducing the overall page load time and improving site performance.
• Customization: You can configure PurgeCSS to include or exclude specific files, directories, or classes based on your project’s requirements.
