## Stacked Icons

fa-twitter on fa-square-o
fa-flag on fa-circle
fa-terminal on fa-square
fa-ban on fa-camera

To stack multiple icons, use the `fa-stack` class on the parent, the `fa-stack-1x` for the regularly sized icon, and `fa-stack-2x` for the larger icon. `fa-inverse` can be used as an alternative icon color. You can even throw larger icon classes on the parent to get further control of sizing.
