Remove Unused CSS Using Developer Tools in Chrome

Are you tired of slow loading times on your WordPress site? One of the reasons why your site may be loading slowly is because of unused CSS. Unused CSS can add extra weight to your site, causing it to load slower than it should. Luckily, you can use developer tools in Chrome to identify and remove unused CSS, and in WordPress sites, you can use WP Rocket plugin to do the same.

First, let’s talk about how to identify unused CSS using Chrome’s developer tools:

Open your website in Google Chrome.

  1. Right-click anywhere on the page and select “Inspect” from the context menu.
  2. In the developer tools window, click on the “Coverage” tab.
  3. Click on the “Reload” button to load the page.
  4. Once the page is loaded, click on the “Stop” button to pause coverage tracking.
  5. You should now see a list of CSS files and how much of each file is being used. Look for files with a lot of unused CSS, as these are the files you want to optimize.

Now that you know which CSS files are not being used, it’s time to remove them. If you’re working on a non-WordPress site, you can manually remove the unused CSS from the files themselves. But if you’re working on a WordPress site, you can use WP Rocket plugin to remove the unused CSS automatically.

WP Rocket is a popular caching plugin for WordPress that can help improve the performance of your site.

One of its features is called “Optimize CSS Delivery”, which removes unused CSS from your site’s CSS files.To use this feature, follow these steps:

Install and activate the WP Rocket plugin.

  1. Go to WP Rocket settings page and navigate to the “File Optimization” tab.
  2. Enable “Optimize CSS Delivery” option.
  3. WP Rocket will now remove any unused CSS from your site’s CSS files, which will help your site load faster.

In conclusion, identifying and removing unused CSS is an important step in improving the performance of your website. By using developer tools in Chrome or WP Rocket plugin, you can easily find and remove the unused CSS, resulting in faster loading times for your site.
