There are already lots of responsive grid and column stacks available for RapidWeaver, so at this point in time you’re most likely questioning the purpose of yet another! AdaptiveGrid is a free alternative to the others available. It was built mostly for use in ThemeFlood themes, in page elements like horizontal containers, block sidebars, FreeStyle banners and fixed footers, but has proven to be useable elsewhere too. AdaptiveGrid is extremely flexible and massively customisable. It also fixes a few annoying flaws to be found in some other responsive layout stacks.
