With such big names as Foundation or Bootstrap, it seems that there is no place for other small and less powerful grid systems. However, not every project demands a bunch of functions and properties that are delivered by default with each of this product. Some concepts (especially the trivial ones) just need a viable base that is tidy, simple and responsive.

There is no point in wasting precious resources to build a one-page website or overloading the portal with a bulky skeleton when you need to showcase a ton of images via a traditional matrix style arrangement. Sometimes minimalist starting kit can do a trick. While it is not universal yet it can give a project a much-needed boost.
