1. CSS attributes, defined like this: icon#attribute1:value1;attribute2:value2

The attributes are specified as a Semicolon-separated-list, just as in HTML

• fa fa-user#color:red
• fa fa-user#color:red;font-size:14px;

1. CSS classes, defined like this: icon#_style:cssClassName1 cssClassName2

The classes are specified as a Space-separated-list, just as in HTML

• fa fa-user#_style:module_prod
