The CMS uses Font Awesome icons, which allow you to display an icon instead of having to use an image. In order to do this, you need to be familiar with HTML.
The recommended way to use Font Awesome icons is the following:
<i class=”YOUR_CLASS” aria-hidden=”true”> </i>
If you would like to have an icon appear but are not familiar with HTML, please submit a request. In your request, please clearly describe what you are trying to achieve, what problem is occurring, and specifically how we can help.
