Hi I have two wordpress sites I'm working to optimize. https://varvy.com/pagespeed/improve-server-response.html
using this to start.
I understand how to combine CSS into one minimized file, same with js. What I don't know is how to then remove the calls from the pages looking for the old files.
EG: site is techgardens dot com. I could ostensibly take all the css from the attached list of stylesheets and add them to my divi child style.css.
But then how do I get rid of all the calls for all the other stylesheets, in a way so that when I upgrade plugins and themes and wordpress, they don't come back? I hope that makes sense. thanks.
