+### Sizing
+
+Cards are block-leve by default, so they'll fill the available horizontal space. Constrain their widths via custom styles, our predefined grid classes, or our grid mixins.

+{% example html %}
+<div class="card" style="width: 20rem;">
+  <h3 class="card-title">Special title treatment</h3>
+  <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
+  <a href="#" class="btn btn-primary">Go somewhere</a>
+</div>
+{% endexample %}
