Metro UI CSS: A Framework For Windows 8-Like Interfaces
After so many years, Windows OS is having a huge overhaul with its Metro UI and it seems like their new style may spread to web apps as well.
Metro UI CSS is a set of styles for creating such interfaces. It is a self-contained solution but can also be used side-by-side with any other frameworks.
There are styles for the popular tiles, images, notices, forms, buttons and typography.
The framework is also a "work in progress" and is mentioned to be enriched with more layout options + features.
