+{% capture example %}
+<div class="jumbotron">
+  <h1 class="display-4">Hello, world!</h1>
+  <p class="lead">This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.</p>
+  <hr class="my-4">
+  <p>It uses utility classes for typography and spacing to space content out within the larger container.</p>
+  <a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a>
+</div>
