‘320 and Up’ is Andy Clarkes personal toolkit. It’s grown to include the files and styles he uses from Twitter’s Bootstrap as well as responsive design libraries and polyfills too. ‘320 and Up’ doesn’t try to do too much. It isn’t a development framework and it doesn’t include grids. It’s simply the files and styles Andy uses when he’s starting a responsive web design.
You can read much much more about the boilerplate on his blog post, but we’ve picked a few things out.
You should note that this is a new version that has moved away from working with HTML5 boilerplate and now works much better as a precursor to Twitter Bootstrap. Andy has included some awesome typography and also some BADA55 icon fonts.
320 and has been built with you LESS people in mind.
