Stacks is a new way to create pages in RapidWeaver: A plugin designed to combine the drag-and-drop simplicity of Blocks with the power of fluid layout. Stacks lets you build pages that flow text to the dimensions of a theme even if the theme has a variable width. You can build flowing columns, flexible rows, and tiles of images. Build columns within columns within rows within columns. Or group a stack of objects inside a box. Almost anything is possible with Stacks.
