+An alert is a banner used to notify a user about a change in status
+ or communicate other information. It can be generated with or without
+ a user triggering an action first.
+```html
+<div class="demo-description">
+  <section class="alerts-page">
+    <pf-alert state="Success">
+      <h3 slot="header">Success alert title</h3>
+    </pf-alert>
+  </section>
+</div>
+```
