Several comments mention Skeleton as possible alternative to Milligram. Unfortunately, as pointed out, Skeleton appears to be dead, i.e., no project activity for a year. I've also used Skeleton in several projects though it required customization of UI element sizes, max grid width, etc. On the whole Skeleton worked well enough and sufficiently lightweight. For all Skeleton users, the project was forked a few months ago and now lives on as skeletonframework, available here: https://github.com/skeletonframework/skeletonframework https://github.com/skeletonframework/skeletonframework
