I've been using the grid system in Twitter Bootstrap on several projects - but can't seem to crack this nut.
I want to place a blue promotion cell in the upper right corner of the grid like this:
Sample code
<div class="row">
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">1</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">2</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">3</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2 big">Promotion</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">4</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">5</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">6</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">7</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">8</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">9</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">10</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">11</div>
<div class="col-xs-6 col-sm-4 col-md-3 col-lg-2">12</div>
</div>

Any help is appreciate
It seems to me the simplest answer would be to place it third in order in the row. This will keep it ordered correctly on the narrowest viewports. Next, use .col-xs-12 just on the .promotion <div>
to achieve the full width on narrow viewports. Finally, use .pull-right to correct the ordering on wider viewports. Your original code is almost there, and with the example you've given I don't see a need to complicate it much.
Check this fork of your fiddle for what I mean: https://jsfiddle.net/rrt22y5p/
