Skeleton is a simple, responsive boilerplate framework to kickstart any responsive project. Skeleton was created by Dave Gamache for a better web. Check out http://getskeleton.com for documentation and details. Skeleton is lightweight and simple.
It styles only raw HTML elements (with a few exceptions) and provides a responsive grid. Nothing more:
Around 400 lines of CSS unminified and with comments
It’s a starting point, not a UI framework
No compiling or installing…just vanilla CSS
The above list is non-exhaustive. Skeleton works perfectly with almost all older versions of the browsers above, though IE certainly has large degradation prior to IE9.
All parts of Skeleton are free to use and abuse under the open-source MIT license.
