Icons can be used as a graphical representation of main ideas that improve your site's navigation, usability, branding, aesthetics, etc. They break up texts by adding ways to present information or to emphasize CTAs (call-to-action).
Zoomforth offers icons called Font Awesome that you can add via the text editors when editing your site.
To add icons in text editors
Pull up the text editor where you want to add an icon.
