	$grid_size = $grid_sizes[ $form['settings']['responsive']['break_point'] ];

	// %1$ sets the Column ID, %2$d Sets the span size, %3$d sets additional column classes
	$grid['column_before'] = '<div %1$s class="' . $grid_size . '-%2$d columns %3$s" style="min-height: 1px;">';
	// the min-height fixes an issue where an empty column doesn't show since foundation uses float:left
