As the name suggests, the purpose of this powerful stack is to append (or prepend) stacks onto other page elements. As an example, you might have a banner area at the top of a webpage that you want to append a special message bar onto. Or as another example, you could use Appender to add some basic stacks to a theme sidebar or footer. Appender is the perfect stack to do all these types of small 'moving' jobs. Appender has a bare-minimum of settings to make setup quick and safe. The only requirement is that you have basic HTML knowledge and the ability to get the class or ID of the element you want to attach stacks onto.
