<figure class="figure">
<img src="..." class="figure-img img-fluid rounded" alt="...">
<figcaption class="figure-caption">
A caption for the above image.
</figcaption>
</figure>
Anytime you need to display a piece of
content—like an image with an optional caption, consider using a <figure>.
Use the included .figure, .figure-img and .figure-caption
classes to provide some baseline styles for the HTML5 <figure> and
<figcaption> elements. Images in figures have no explicit size,
so be sure to add the .img-fluid class to your <img> to make it responsive.
