 * Hello
    Is it possible to make Autoptimize’s combined CSS file load asynchronously
   and add such possibility in the Settings page?

 * that would be the “inline & defer”-option user45, leaving the to-be-inlined critical/
   above-the-fold CSS field empty. do take into account that your site will first
   display without the CSS’s styling for a second or so (aka FOUC or flash of unstyled
   content).

 * Inline & Defer is useless because the noscript css file is in the head. Google
   Page Speed indicates that file. It should be in the footer. How can I move it
   to the footer or perhaps you will change that in the next version?

 * I just found out, “noscript” is not visible for Google Page Speed. “Inline & 
   Defer” just do not work.
 * I can see noscript code, ordinary CSS link in the head, LoadCSS in the footer.

 * inline & defer works just great (and code-wise works identically on mobile & 
   desktop) in the sense it effectively postpones loading of the CSS, but google
   pagespeed insisght will still mark the deferred CSS as render blocking for the
   simple reason the _real_ rendering indeed has to wait until the deferred CSS 
   is loaded.
 * the problem is you’re merely deferring and not inlining (where the inlined CSS
   can do the initial rendering so the deferred CSS is not considered render-blocking
   any more). so, now that we’ve reached that conclusion; you really should look
   into the critical CSS stuff and inline your above-the-fold CSS. have look at 
   [the FAQ](https://wordpress.org/plugins/autoptimize/faq/) for info on that topic
   🙂

 * I did that and have alongside “CSS inline and Defer”, another ordinary CSS link
   in the Head.

 * the only ordinary CSS remaining in head would be non-local ones (on 3rd party
   domains, e.g. google fonts and stuff), which AO doesn’t ever touch.
 * but if you can provide your URL here, I’ll be happy to have a look and propose
   improvements to your config if possible 🙂
