I have created a grid structure for my website using bootstrap 3. It looks great on desktop, but when I resize the window it does not switch to mobile or tablet view. What am I doing wrong? On desktop, I want each panel to take up 1/6 of the row, and on mobile, 1/3.
<div class="row" id="features">
<div class="col-lg-2 col-md-2 col-sm-2 col-xs-2">
<div class="panel odd">
<img src="images/treatment.png" alt="Treatments">
<span>Treatments</span>
</div>
</div> <!--panel-->
<div class="col-lg-2 col-md-2 col-sm-2 col-xs-2">
<div class="panel odd">
<img src="images/treatment.png" alt="Treatments">
<span>Treatments</span>
</div>
</div> <!--panel-->
<div class="col-lg-2 col-md-2 col-sm-2 col-xs-2">
