I have noticed that when I add column number 1, column number 2 moves down. But when I delete column number 1, column number 2 moves up as expected, similar to column number 3. I'm unsure why this is happening?
<div class="row">

<div class="col-xs-8 row">

<div class="col-xs-12" style="height:205px;border: 1px solid blue;"> <span class="center"></span></div>

<div class="col-xs-2" style="height:800px;border: 1px solid red;"><span class="right"></span></div>
