Remove unused CSS

The unused CSS is being reported as being Autoptimize’s, but AO merely aggregates all the CSS provided by your theme & plugins, so if you (really) want to tackle “remove unused CSS” then you should look into your theme & plugins (you might be able to get some improvement using e.g. “plugin organizer” to only allow plugins to work on specific pages). Moreover the unused CSS will likely be different for different pages (or parts of your site), so that would lead to different autoptimized CSS-files being loaded on different pages.

My suggestions; don’t obsess over GPSI “opportunities” but focus on real spead (time to first byte, time to start render/ significant paint, onLoad time, …) instead 🙂

hope this clarifies,
