Berq Used CSS – Remove Unused CSS Automatically

Every WordPress theme and plugin loads CSS for every possible feature – menus, sliders, pop-ups, forms, even on pages that don’t use any of them. All that extra CSS slows your site down and hurts your Google PageSpeed score.

Berq Used CSS fixes this automatically.

It scans each page of your website, figures out exactly which CSS rules are actually used, and saves a trimmed-down version. From that point on, visitors get only the CSS they need – nothing more. Pages load faster, your PageSpeed score goes up, and you didn’t have to touch a single line of code. It works with every WordPress theme, plugin, and page builder right out of the box.

How it works:

1. A visitor lands on a page for the first time – the plugin analyses the page and generates a lean version of its CSS before the page finishes loading.
2. That same visitor, and everyone after, gets the smaller CSS file, and the page loads noticeably faster.

Features:

• 100% free – no account, no sign-up, and no data sent to external servers
• Automatically generates used CSS for every page on first visit.
• Three stylesheet loading modes: keep originals, load them after interaction, or remove them entirely
• Exclude any URL or CSS selector you want to keep untouched
• Strip web font declarations and background images from the generated CSS to save even more weight
• Updates automatically when you save a post, update a plugin or theme, or change your design in the Customizer.
• Works alongside cache plugins like WP Rocket, LiteSpeed Cache, W3 Total Cache, WP Super Cache, SiteGround Optimizer, Nginx Helper and more
• Works with every WordPress theme and plugin – no compatibility issues
