This is a simple demo of how the panel options work. Each panel option has it's own class, except four up because it's default. Classes can be any of the following:
This class is added to the (.panels) div. Just make sure that there are the appropiate amount of panel items in respect to the panel option you chose.
In addition, there is a new class created that pairs with .panel-item. It's called (.alternate-panel-item). This is a div designed to display an ad that does not pop up, but rather goes to another page. Along with that, the class (.item-expands) must be added to any panel item that you want to pop up.
No class, this is default
Add class(.three-up-top) to .panels
Add class(.three-up-bottom) to .panels
Add class(.three-up-left) to .panels
Add class(.three-up-right) to .panels
Add class(.two-up-vertical) to .panels
Add class(.two-up-horizontal) to .panels
Add class(.one-up) to .panels
