They provided me with this code snippet
<iframe width="424" height="916" src="//invis.io/U5574OIA3" frameborder="0" allowfullscreen></iframe>However, I am unsure of how to properly embed it. I attempted to insert the line into my website but nothing seems to appear.
If needed, I can offer more information. Thank you in advance.
update:
<div class="container">
<div class="row project">
<div class="ten columns offset-by-one">
<h class="pageheadproject">Final Result</h>
<p class="divider">~</p>
<p class="subheadproject">User Scenario</p>
<p class="pagecontent2-first"> Sample Text </p>
<iframe width="424" height="916" src="//invis.io/U5574OIA3" frameborder="0" allowfullscreen></iframe>
</div>
</div>
I added a border to the iframe and now it appears like this https://i.sstatic.net/RqglO.png
