I’ve been looking at Google PageSpeedInsights and my newly-finished website scored just 25/100 for mobile. I want to reduce “render-blocking resources” and css is one of the things I can improve.
There are about 15 screen-dependant rules which are currently written in the Customizer CSS.
Some are about min-width and some are about max-width.
They are for extra classes that I have created and for rules that cannot be modified via the customiser.
