Flowtime.js is designed to perfectly fit your viewport and is based on a solid display: inline-block; foundation.

This framework doesn’t style your presentations or sites for you but it takes care of all the annoying things like navigation and deep-linking, so you are free to style every single element of your design as you like. But for the ones who need a ready-to-use tool it comes with a default theme that you can edit or you can add new themes just by linking your CSS files.
