Really simple wordpress shortcode column system… relies on scss and Bourbon Neat to work.

_col.scss

.col {
  @include span-columns(4);
}

@for $num from 1 through 12 {
  .col-#{$num} {
    @include span-columns($num);
    @include omega(#{12/$num}n);
  }
}

functions.php

<?php
  function column_func( $atts, $content="" ) {
    $divclass = "col";
    if ($atts['number'] != "") {
      $divclass = "col-" . $atts['number'];
    }
    return "<div class='" . $divclass . "'>" . $content . "</div>";
  }
  add_shortcode( 'column', 'column_func' );
?>

This works on the default 12 column layout, and also wraps boxes nicely thanks to omega!
