Skeleton seems unmaintained. https://github.com/dhg/Skeleton

Yes it seems so. But there are forked repositories that are being maintained. They are

1. Skeleton framework (https://github.com/skeleton-framework/skeleton-framework) and

2.Skeleton Plus (https://github.com/oltmannsdaniel/skeleton-plus)

I like skeleton plus because of the responsive menu. The colours are not so good :P
