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 ### Other Products Also check out our other WordPress products. * [BerqWP](https://berqwp.com/) * [Berq Markdown](https://wordpress.org/plugins/berq-markdown/) * [WP Replai](https://wpreplai.com/) ## Screenshots [⌊Settings page⌉⌊Settings page⌉[ Settings page ## Installation 1. Upload the plugin to your site via **Plugins Add New Upload Plugin**, or search for „Berq Used CSS“ in the plugin directory. 2. Activate the plugin. 3. Visit your website – used CSS generates automatically as each page is first visited. No configuration needed to get started. Optional: go to **Settings Berq Used CSS** to choose a stylesheet loading mode, exclude specific pages, or clear the cache. ## FAQ ### Do I need to create an account or sign up for anything? No. Berq Used CSS works entirely on your own website. There is no account to create, no sign-up required, and no data is sent to any external server. ### Will this break my website’s design? No. The very first visit to any page generates the used CSS and serves it on that same visit – your layout and styling stay exactly as intended, just with the unused CSS stripped out. ### How long does it take to generate used CSS for my pages? Generation happens during the first visit to a page, before the page finishes loading. That first visit may take a little longer while the plugin analyses the page, and every visit after that – including that same one – gets the trimmed CSS. ### What happens when I update my theme or a plugin? The plugin automatically clears the saved CSS and re-generates it. This happens whenever you save a post, update a theme or plugin, make changes in the Customizer, or clear cache in Elementor. ### Which stylesheet loading mode should I choose? Start with **Load immediately** (the default) – this already gives you a faster page by serving lean CSS. If you want the maximum speed boost, try **Load after interaction**, which delays the original stylesheets until the visitor scrolls or clicks. Use **Remove completely** only if you are confident the generated used CSS covers everything your pages need. ### Does it work with my theme and plugins? Yes – Berq Used CSS works with every WordPress theme and plugin without any configuration. It reads the CSS that your pages actually output, so it doesn’t matter whether you use Elementor, Divi, WPBakery, Gutenberg, WooCommerce, or any other tool. If your page loads in a browser, the plugin can generate used CSS for it. When you save changes in Elementor or switch themes, the saved CSS is automatically cleared and re-generated. ### Will it affect my Google PageSpeed / Core Web Vitals score? Yes – removing unused CSS directly reduces the amount of render-blocking CSS the browser has to process, which improves First Contentful Paint (FCP) and other Core Web Vitals metrics. ## Rezensionen Zu diesem Plugin liegen noch keine Rezensionen vor. ## Mitwirkende und Entwickler „Berq Used CSS – Remove Unused CSS Automatically“ ist Open-Source-Software.
