There are 8 stylistic module class suffixes, these add a unique style variation to the module: title1-4 and box1-4; and various additional structural suffixes, these affect the layout and metrics of the module.
Furthermore, you can also add FontAwesome icons into the Module Class Suffix. You will get a small sized icon to the left of the title. Suffixes are in the icon-NAME format such as icon-star, as shown on the Typography page.
