Is there any good way to avoid render blocking css (google page speed) from Wordpress. Probably more complex, but find a way to add in theme development. It means, not something very specific but global.
I already try to move css files into the footer, nothing change.
I know there is a way by loading css with js to make them asynchron. Basically it creates the link tag only when it reach the inline script. But is this a correct way to add this in a theme (it means not doing any register_style etc)? Is there any other way?
