Syntax

This grid system uses a 12-column grid and is fully responsive. Columns are wrapped within a grid class.

<div class="grid">
    <div class="column-xs-12 column-md-12">1</div>
  </div>

Grid

Use column-xs-*, column-sm-*, column-md-*, or column-lg-* classes with values 1 through 12 to indicate the number of columns. By default, all columns are the same height.
