What’s the purpose of not used CSS?
Unused CSS is a reference to CSS files that appear on a site but are they are not required to allow the website to load. When a person visits an online site and the browser is able to download, read and process any external stylesheets that are on the page before it is able to display the contents.
If CSS is on the page, but it isn’t being used the browser will use its time on it, which can slow down the loading speed of the site. Examples of this include contact form plugins that typically load their CSS across the entire website even though it’s not being used on specific pages.
Theme developers may be a part of the problem by adding excessive CSS in the style.css file that will be loaded every time the site loads. While a single unusable CSS file isn’t an issue, a significant quantity of unusable CSS could significantly affect the loading time of websites.
