Indeed, most scenario, around 70% – 80% of a page’s CSS codes are redundant, and can be removed without affecting the overall visual. This happens mainly because WordPress themes and plugins are created as generic solutions that includes a bunch of features that may or may not be used on a particular page. Example: A theme may come with a bunch of features such as _slider_, _carousel_, _animation_ and etc, but your home page may use only the _slider_ feature and your about page may use only the _carousel_ feature. However, for practical reason, it’s virtually impossible to selectively include only the required CSS rules for the features that were enabled on a particular page. This is where the CSS Optimizer becomes useful. The plugin make calls to [ZippiSite](https://zippisite.com)‘ s CSS Optimizer API to find the required CSS rules on a particular page, and remove the ones that are not needed. ## 屏幕截图 * [[ * Remove Unused CSS to pass Google PageSpeed Insights (Core Web Vitals) * [[ * Settings page, the only place you need to configure. ## 常见问题 ### Is the CSS Optimizer API free to use? It’s free to use with a quota of 150 API hits per months. Note that API hits does not equals page views. In our tests on real world websites, 150 API calls is able to serve approximately 1,000 monthly page views. In other words, the Free Plan should suffice for small websites. If you require more API quota, paid plans are available, starting from as cheap as $3 for 800 monthly API calls – approximately 5,300 monthly page views. ### What happens if there are styling issues after using this plugin? We provide free support for all plans – even free plans. We’ll reply within 12 hours for paid plans, and within 24h for free plan. ### What this plugin really does? Will it add extra burden to my server? What this plugin does is to make calls to our API hosted on our server. The real heavy-lifting is done on our server, so you don’t need to worry that the plugin will require extra resources. ## 评价 ![](https://secure.gravatar.com/avatar/bfb00f8366e3a779a410536f4aa22aaa3a1ce0be5b3b2e212247b61ff7225649? s=60&d=retro&r=g) ### 󠀁[Pest plugin](https://wordpress.org/support/topic/pest-plugin/)󠁿 [Bahus](https://profiles.wordpress.org/bahus/) 2023 年 3 月 3 日 The plugin simply catastrophically eats up space on the hosting.The site is 5.9 gigabytes.
