optimize css delivery showing 3 items to change

Well, up until recently the widely used best practice was to have all the CSS loaded from the HEAD of the HTML in a limited number of external files. Google now advices otherwise, specifically for mobile.

There is an entry in the FAQ that discusses how you can safely defer CSS (warning: not that easy).

In the upcoming version 1.8 you also will be able to inline all CSS, which will certainly improve your pagespeed-score but might negatively impact your real page speed if you have users with an important pages/ visit ratio (as all CSS is downloaded with every page, instead of only just once in a cached external file).

All of this, however, does not apply to the external CSS (your Google Font). If you want to eliminate CSS render blocking, you might want to consider using native fonts instead (always a nice performance improvement, actually).

hope this helps,
