1) Cache dynamic CSS: I use a CDN and a caching plugin (w3 total cache) should I still go ahead and activate this to boost site performance? Please know that I use a decent amount of custom CSS in the “additional CSS section of customizer.
2) Load essential icons only: I use fontawesome icons at some places. Should I enable this (will the font awesome icons used on the site work normally after that?).
P.S. I use the following code to generate an icon in my bullet lists. it appears good on desktop (I have linked the page using the code in URL section. Please search for “wpengine” to view it).
The problem is it doesn’t load on mobile and gives an unsupported icon. How can we fix that?
