Bootstrap combining rows (rowspan)

Divs stack vertically by default, so there is no need for special handling of “rows” within a column.

div {
  height:50px;
}
.short-div {
  height:25px;
}

<div class="container">
  <h1>Responsive Bootstrap</h1>
  <div class="row">
    <div class="col-lg-5 col-md-5 col-sm-5 col-xs-5" style="background-color:red;">Span 5</div>
    <div class="col-lg-3 col-md-3 col-sm-3 col-xs-3" style="background-color:blue">Span 3</div>
    <div class="col-lg-2 col-md-2 col-sm-3 col-xs-2" style="padding:0px">
      <div class="short-div" style="background-color:green">Span 2</div>
      <div class="short-div" style="background-color:purple">Span 2</div>
    </div>
    <div class="col-lg-2 col-md-2 col-sm-3 col-xs-2" style="background-color:yellow">Span 2</div>
  </div>
</div>
<div class="container-fluid">
  <div class="row-fluid">
    <div class="col-lg-6 col-md-6 col-sm-6 col-xs-6">
      <div class="short-div" style="background-color:#999">Span 6</div>
      <div class="short-div">Span 6</div>
    </div>
    <div class="col-lg-6 col-md-6 col-sm-6 col-xs-6" style="background-color:#ccc">Span 6</div>
  </div>
</div>
