Based on this answer, which is very similar: https://stackoverflow.com>
I would suggest 2 angles to attack this problem: borders or a series of lines. Here is the demo daemon (jsfiddle) .
Below the sample for the background option, the only drawback is that you do not actually control the line width unless you use complex backgrounds.
<div class="row myBackground"> <div class="span6">span6</div> <div class="span6">span6</div> </div>
.row.myBackground { background: #F00; } .row.myBackground > [class*="span"] { background: blue; }
