Skeleton is made to scale to also fit mobile browsers, following the principles of responsive web design. Does Bootstrap offer the same?
Yes Twitter Bootstrap's 2.0 version is based on responsive web design. look at their website: http://twitter.github.com/bootstrap/. You will have to play around with it when you download, cause the download version does not have it. You will have to rename the responsive css, best option is to look at their website and try to reverse engineer it.
