Using Font Awesome Icons
The icons used in Canvas are from the Font Awesome icon library. The classes take the format ‘fa-classname’. So for example a home icon class is called ‘fa-home’. To find out all the classes you can use this reference: http://fortawesome.github.io/Font-Awesome/icons/
Please note: at this time not all the icons from the Font Awesome library work as Canvas does not use the most up to date version. So you may find a small number (very few) that do not work.
