How do I combine two icons?
To stack multiple icons, use the fa-stack class on the parent HTML element of the 2 icons you want to stack. Then add the fa-stack-1x class for the regularly sized icon and add the fa-stack-2x class for the larger icon. fa-inverse can be added to the icon with the fa-stack-1x to help with a knock-out looking effect.
