Reduce unused CSS is one of the PageSpeed Insights recommendations you’ll likely get when testing your site speed. In plain English, it means that some CSS files affect your site loading time — and you should address the issue to make your website faster.
ℹ️ 80% of your CSS files are useless 80% of the time!

Remove Unused CSS
with WP Rocket
You’ll get stellar results in no time, without touching the code!
Automatic Detection
WP Rocket automatically collects all the stylesheets and scripts found on each page of your website to exclude unused CSS from the HTML.
It is easy and straightforward: no effort or technical knowledge is required!
Time to say bye to all that excess code just bloating your website, wouldn’t you say?
Easy Customization
Need to exclude something? We’ve got you covered.
Files and patterns can be excluded by using the CSS Safelist.
Once the Remove Unused CSS option is enabled, WP Rocket reveals a text area where you can enter the CSS files (or CSS classes or IDs) you specifically do not want to remove.
Immediate Results
The Remove Unused CSS feature will reduce your overall page size and thus page load time.
Cherry on top, you should also see better PageSpeed Insights scores when enabling it. More specifically, it should have a significantly positive effect on the Largest Contentful Paint (LCP – measures loading performance) and the First Input Delay (FID – measures interactivity) metrics.

Muuuuch better than Autoptimize, W3 Total Cache etc.
What makes it really awsome is the cache preload and remove render blocking CSS!
