When building a website, using a CSS framework like Bootstrap or MaterializeCSS can often lead to having an abundance of unused styles. This is where PurgeCSS shines, helping you clean up your CSS files by removing the unnecessary selectors that your project doesn’t utilize. In this guide, we’ll explore how to set up and use PurgeCSS to maintain a cleaner, more efficient website.

What is PurgeCSS?

PurgeCSS is a tool that analyzes your website’s content and your CSS files. It matches the selectors in your CSS with the actual selectors used in your HTML files. This results in the removal of any unused CSS, leading to a significant reduction in the size of your CSS files. Picture it like a tidy-up session in your closet, where you keep only the clothes you wear and donate the rest!

Getting Started with PurgeCSS

Installation

To install PurgeCSS, you can use npm (Node Package Manager). Run the following command in your project’s directory:

npm install purgecss --save-dev

Usage

Once installed, you can easily import and utilize PurgeCSS in your project by following the steps below:

import { PurgeCSS } from 'purgecss';

const purgeCSSResults = await new PurgeCSS().purge({
  content: ['./*.html'],
  css: ['./*.css'],
});

In the snippet above, we are importing the PurgeCSS module and calling the purge method. You will need to specify the paths to your HTML and CSS files, allowing PurgeCSS to do its work effectively. Think of it as sending your unworn clothes to a donation center after sorting through them.

Additional Resources and Configuration

PurgeCSS also offers various configuration options, as well as integration with frameworks such as Webpack, Gulp, and PostCSS. You can find more detailed guidance and documentation on their official website.

Troubleshooting

• If you find that some of your necessary CSS is being removed, check your HTML files to ensure that all selectors are being used correctly.
• Make sure that you are referencing the correct paths for your content and CSS files in the code.
• If you are using JS frameworks, double-check that all dynamic classes are accounted for—PurgeCSS might not detect them in static analyzers.
