Sorry I forgot the layout I used in the example:
<div class="container">
<div class="row">
<div class="col-12 span12">
<h3>Course Page Layout Example</h3>
<div class="col-3 span3">
<h4>Overview</h4>
<p>Lorem ipsum dolor sit amet, eu iisque legimus eum, ubique
mandamus suavita te cu vis, qui in consul sensibus.</p>
</div>
<div class="col-5 span5">
<h4>Questions</h4>
<p>1) Question one.</p>
<p>2) Question two.</p>
</div>
<div class="col-4 span4">
<h4>Help</h4>
<p>Nostrud consulatu consequat, nobis vulputate pertinacia at mea.</p>
</div>
</div>
</div>
</div>
Hope that helps?
Also just so you know, I added two lots of styles so that it would work in this forum, as this site uses Bootstrap 4 and Adaptable uses Bootstrap 2.3.2. which means
class="col-12" is the same as class="span-12"
You will find some more instructions in the following link:
