HELP
If Font Awesome isn't already being called on your site, you'll need this in your <head> section:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css">
How to use these codes in your CSS: .myclass:before { content: "\f0f9"; font-family: 'FontAwesome'; }
