    <div class="container"><div class="height1">1</div></div>
    <div class="container"><div class="height1">1</div></div>
    <div class="container"><div class="height1">1</div></div>
    <div class="container"><div class="height1">1</div></div>
    <div class="container"><div class="height1">1</div></div>
    <div class="container"><div class="height1">1</div></div>
    <div class="container"><div class="height1">1</div></div>
    <div class="container"><div class="height1">1</div></div>
    <div class="container"><div class="height1">1</div></div>
</div>

.col-fluid div.container
{
  padding-top:10px;
