+
+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.
+
+{% capture example %}
+<figure class="figure">
+  {% include icons/placeholder.svg width="400" height="300" class="figure-img img-fluid rounded" %}
+  <figcaption class="figure-caption">A caption for the above image.</figcaption>
+</figure>
+{% endcapture %}
+{% include example.html content=example %}
+
+Aligning the figure's caption is easy with our [text utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/text/#text-alignment).
