From Portals

To set the system font modify the ewaress.css file

   /*font controlled here*/
   body, table, td 
       font-size: 13px;
       color :black;
       font-family: Arial, Sans-Serif;

In this instance you can see that we set the font to be size 13px and family to use "Arial, Sans-Serif".

Icons are use from Font Awesome 4.6.1

Within the SQL box on the portal menus set the icon to be the name of the icon

 e.g. fa fa-home fa-lg
         fa-lg - sets icon size
To increase icon sizes relative to their container, use the fa-lg (33% increase), fa-2x, fa-3x, fa-4x, or fa-5x classes.
Or just use e.g fa fa-home for default size.
