This theme is responsive, the layout will accommodate all screen sizes. While built-in features cover most site needs, only use responsive pages, plug-ins, and stacks – with responsive themes.
For slideshows, we offer SuperFlex.
For columns, we offer Production.
For galleries, we offer Photo.
These solutions are called “stacks”, and require the Stacks plugin. While stacks are sold separately, these stacks can be used in any theme.
