Move columns to the right using .offset-md-* classes. Each class increases the left margin of a column by a whole column. For example, .col-md-offset-4 moves .col-md-6 over four columns.
<div class="row">
<div class="col-md-4 col-md-offset-6">
.col-md-4 .col-md-offset-6
</div>
</div><!-- /row -->
<div class="row">
<div class="col-md-3 col-md-offset-1">
.col-md-3 .col-md-offset-1
</div>
</div>
