We’ve been using the bootstrap frontend framework for a few of our recent projects here at NNM, so I thought I would pop a link on our site!
It was originally developed by a couple of guys at Twitter and released as open source in 2012, they intended to create a responsive frontend framework to improve consistency across their site and I think they hit the nail on the head.
Using the bootstrap classes, developers can quickly build sleek responsive webpages and sites, a really handy tool.
