<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>

Answer 1

You'd have to include both of them inside a div each, which would be conditionally rendered according to viewport size.
For the div with <= 499px, you'll need to enclose the whole part in:
<div class="d-md-none">
</div>
And for the div with >=500px, you'll need to enclose the whole part in:
<div class="d-none d-md-block">
</div>
