The div I'm working with appears smaller than its content when using the Chrome DevTools. The discrepancy is highlighted by the black and red lines in the image below.

You can see the code here:
<div class="col-md-12">
<div id="survey" class="survey"></div>
</div>
I suspect that the issue may be related to the flex property of my cards, but I'm not entirely certain.
