Thread:Project:Support desk/RL: Eliminate render-blocking JavaScript and CSS in above-the-fold content/reply

Just forget it.

I have tried exactly the same a few days ago; if you speak German I can link you the thread from the German WP. It is just not possible - at least not in a reasonably maintainable way.

I cannot say why Google does not complain for the WP page, but in my tests it already was enough to place any style defintion in the HTML directly. Then Google was happy. That this style did not apply to content above the fold, was not interesting for Google. Also that all the other styles, which did apply above the fold, still were in the blocking stylesheet also was not interesting for Google. I had not improved the situation, but Google did no longer show the error. To cut a long story short: Do not give much about Google's warnings in this regard. They don't mean much.

Google will already give a way better score, if the different JavaScripts were concatenated into one instead of into four files. This will also save a few connection on load. At least that would be what I would try fixing first. However, I do not know, how RL internally decides to merge or not to merge different styles. It might be that, if we just always merge everything, we later have way more entries in cache, which in fact are hardly ever used as they are to special...
