Don't want your columns to simply stack in smaller devices? Use the extra small and medium device grid classes by adding .col-xs-* .col-md-* to your columns. See the example below for a better idea of how it all works. <!-- Stack the columns on mobile by making one full-width and the other half-...

Build on the previous example by creating even more dynamic and powerful layouts with tablet .col-sm-* classes. <div class="row"> <div class="col-xs-12 col-sm-6 col-md-8">.col-xs-12 .col-sm-6 .col-md-8</div> <div class="col-xs-6 col-md-4">...

In addition to prebuilt grid classes for fast layouts, Bootstrap includes Less variables and mixins for quickly generating your own simple, semantic layouts. Variables Variables determine the number of columns, the gutter width, and the media query point at which to begin floating columns. We use ...
