I am currently working on embedding two websites onto my own website. The idea is to showcase these websites side by side within a custom-sized iframe that adjusts responsively based on the viewport size. To achieve this, I am utilizing Bootstrap 4's column and row capabilities. However, I am facing an issue with the spacing between the columns being too excessive: https://i.sstatic.net/Evr5g.png
It's worth noting that this question has been asked before, and I have explored Forum A and Forum B, but unfortunately, neither of them provided a satisfactory solution to my problem.
Here is the code snippet:
<div class="col-auto mb-3">
<div class="card" style="border: none;">
<div class="card-body">
<div class="card container-fluid justify-content-center" style="margin-top: 80px; min-width: 44vw; border: 0;">
<div class="card-header" style="background-color: #3c525d; color: white; width: 100%;">
<b>EXAMPLE WEBSITE
<span style="float: right; font-size: 20px;">
<a style="color: white;" href="https://getbootstrap.com/docs/4.0/getting-started/introduction/">
<i class="fas fa-expand"></i>
</a>
</span>
</b>
</div>
<div class="card-body" style="padding: 0;">
<iframe src="https://getbootstrap.com/docs/4.0/getting-started/introduction/" style="width: 100%; height: 600px; border: none;"></iframe>
