<div class="row">
<div class="col-md-3">
ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
</div>
<div class="col-md-5 col-md-offset-1">
ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
</div>
<div class="col-md-3" >
fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
</div>
</div>
А если добавить пробелы - то происходит
<div class="row">
<div class="col-md-3">
<p>text in bs text in bs text in bs text in bstext in bs text in bs text in bs text in bstext in bs text in bs text in bs text in bs</p>
</div>
<div class="col-md-5 col-md-offset-1">

</div>
<div class="col-md-3" >
