Parallaxis is a single page design theme that uses blocks of content to develop it's pages. The provided Parallaxis Block stack is used for content, up to 10 (ten) Parallaxis Block stacks can be used in a single Stacks page.
The provided Parallaxis Menu stack is used to provided links between all stacks. Although page blocks can only be linked using the Parallaxis Menu stack, the use of this stack is not mandatory because the Stacks page can scroll up and down 100% to reveal all content.
Note how Parallaxis has no standard Rapidweaver navigation menu. This is because all content blocks are developed inside one single Stacks page.
