What is Skeleton?
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.
Is Skeleton for you?
You should use Skeleton if you're embarking on a smaller project or just don't feel like you need all the utility of larger frameworks. Skeleton only styles a handful of standard HTML elements and includes a grid, but that's often more than enough to get started. In fact, this site is built on Skeleton and has ~200 lines of custom CSS (half of which is the docking navigation).
