I'm having trouble adjusting the column order for small screen resolutions in Bootstrap 4.1. I've added the order prefix but nothing seems to be changing. Here is a snippet of my HTML code. Can anyone offer assistance?
<div class="container-fluid office-spaces">
<div class="col-md-12 col-xs-12 first-layout">
<div class="col-md-6 order-2 order-md-1">
<div class="office-spaces-slider">
<div class="img-wrapper">
<img class="img-responsive" src="theme/images/interior2.jpg" alt="interior2">
</div>
</div>
</div>
<div class="col-md-4 order-1 order-md-2">
<div class="col-md-6 col-xs-12">
<hr>
<h3>OFFICE SPACES</h3>
</div>
<div class="col-md-6 col-xs-12">
