<p>“Remove Unused CSS” is frequently flagged in Google’s PageSpeed Insights. 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.</p>
<p>Example: A theme may come with a bunch of features such as <em>slider</em>, <em>carousel</em>, <em>animation</em> and etc, but your home page may use only the <em>slider</em> feature and your about page may use only the <em>carousel</em> 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.</p>
<p>This is where the CSS Optimizer becomes useful. The plugin make calls to <a href="https://zippisite.com" rel="nofollow ugc">ZippiSite</a>‘s CSS Optimizer API to find the required CSS rules on a particular page, and remove the ones that are not needed.</p>
