The F2fw framework currently consists of many common CSS classes that a front-end developer will most likely to use in its development, a library of components containing columns, breadcrumbs, menu, forms, etcetera.
Following the former article(1) on CSS sprites, the btt class is now included in F2fw with an addition of both the ico and arr classes that have the same properties as btt, except they are intended for icons and arrows, respectively.
Previously, it was commonly called F2, at Artmov, but in 2011 it was renamed in F2fw and publicly released. It is currently hosted at Github: https://github.com/artmov.
This article was updated in 2011.
