Divi theme has some built in icons that you can call in a style sheet such as the following:

.someclass:before {
font-family: “ETmodules”;
content: “\6c”;
}

This will give me the icon of a pad and pencil.

I originally got this tip from Josh Hall on YouTube. Thanks for sharing Josh!

This issue I had was being able to figure out the code number for which Icon. The code numbers do not match Font Awesome font codes.

I finally found Elegant Themes cheat sheet for these icons.

I hope this helps someone else out there…
