I am currently developing a clients website and on their home page there is a "Gallery" feature similar to general WordPress themes that have a "Featured Icon Box" function, where you can select any icon including Font-awesome and default WordPress icons along with a title and text.
In saying that I want to add my (already added) font-awesome icons in my assets to the gallery feature you guys already have. Screenshot attached to show what I am focusing on, and another screenshot with my focus intent.
Intended result is to use Fontawesome along with your already existing icon set
(Feature Box - Icon and text example)
