Skeleton is a small collection of CSS files that can help you rapidly develop sites that look beautiful at any size, be it a 17" laptop screen or an iPhone. Skeleton is built on three core principles:
Skeleton has a familiar, lightweight 960 grid as its base, but elegantly scales down to downsized browser windows, tablets, mobile phones (in landscape and portrait). Go ahead, resize this page!
Skeleton is a tool for rapid development. Get started fast with CSS best practices, a well-structured grid that makes mobile consideration easy, an organized file structure and super basic UI elements like lightly styled forms, buttons, tabs and more.
Skeleton is not a UI framework. It's a development kit that provides the most basic styles as a foundation, but is ready to adopt whatever your design or style is.
Skeleton's base grid is a variation of the 960 grid system. The syntax is simple and it's effective cross browser, but the awesome part is that it also has the flexibility to go mobile like a champ. Go ahead, resize the browser and watch as the layout reacts!
