bootstrap_ms.css.scss

// Bootstrap Mid-Small - col-ms-* - the missing grid set for Bootstrap3.
//
// This is a hack to fill the gap between 480 and 760 pixels - a missing range
// in the bootstrap responsive grid structure.  Use these classes to style pages
// on cellphones when they transition from portrait to landscape.
//
// NOTE: Here I use SASS instead of LESS for styling.  To convert to LESS
// replace '$screen' with '@screen' and '$grid' with '@grid'.
//
// See https://github.com/twbs/bootstrap/issues/10203 for more info.
//
// Columns, offsets, pushes, and pulls for the ms device range, from phones
// to tablets.
//
// Note that `.col-ms-12` doesn't get floated on purpose—there's no need since
// it's full-width.
