When running a GTmetrix report, a common audit that you may encounter is Reduce Unused CSS. In plain English, it means that some CSS files affect your site loading time — and you should address the issue to improve speed.
ℹ️ 80% of your CSS files probably don’t do anything 80% of the time!
WP Rocket offers a powerful feature that allows you to tackle unused CSS in one click to save you precious seconds of page loading times.

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 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.
Outstanding 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 GTmetrix 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.

Wonderful plugin, very easy to use and didn't break my theme. From 'F' to 'A' on GTmetrix in no time. Very happy!

WP Rocket has a new customer for life
With WP Rocket, and some other suggested improvements my site scores 100% on GTmetrix for speed and structure. The best thing is I didn't really do much with the plugin, just activate it, pretty much leave it as is out of the box and let it do its thing.
