Hello sorry for the late reply , i didn’t get a mail notification and i just saw your post.
As soon as you enable the plugin and set it up from the options page you can get your “above the fold” css on the bottom of your homepage, you can then paste it in Autoptimize plugin or any other to “inline” it.
Hi, I too am wondering how to use this. I followed the video. I use Autoptimize. Do I just paste that code into the Inline and Defer CSS field? Do I have to manually go into my CSS files and remove this code as well?
As it is now, I just entered that blob of code into Autoptimize’s input field, but don’t notice any difference on Google Page Speed Insights. It’s still telling me to optimize delivery of the giant CSS file generated by Autoptimize.
