patternfly/tests-src/_includes/widgets/communication/toast-warning.html

This reference implementation of PatternFly is based on [Bootstrap v3](http://getbootstrap.com/). Think of PatternFly as a "skinned" version of Bootstrap with additional components and customizations.

<div class="toast-pf alert alert-warning alert-dismissable">
  <button type="button" class="close" data-dismiss="alert" aria-hidden="true">
    <span class="pficon pficon-close"></span>
  </button>
  <div class="pull-right toast-pf-action">
    <a href="#">Reload Server</a>
  </div>
  <span class="pficon pficon-warning-triangle-o"></span>
  The server configuration changed.
</div>
