+
+## Examples
+
+Alerts are available for any length of text, as well as an optional dismiss button. For proper styling, use one of the eight **required** contextual classes (e.g., `.alert-success`). For inline dismissal, use the [alerts jQuery plugin](#dismissing).
+
+{{< example >}}
+{{< alerts.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<div class="alert alert-{{ .name }}" role="alert">
+  A simple {{ .name }} alert—check it out!
+</div>{{- end -}}
+{{< /alerts.inline >}}
+{{< /example >}}
+
+{{< callout warning >}}
+{{< partial "callout-warning-color-assistive-technologies.md" >}}
+{{< /callout >}}
+
+### Link color
+
+Use the `.alert-link` utility class to quickly provide matching colored links within any alert.
+
+{{< example >}}
+{{< alerts.inline >}}
+{{- range (index $.Site.Data "theme-colors") }}
+<div class="alert alert-{{ .name }}" role="alert">
+  A simple {{ .name }} alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
+</div>{{ end -}}
+{{< /alerts.inline >}}
+{{< /example >}}
+
+### Additional content
+
+Alerts can also contain additional HTML elements like headings, paragraphs and dividers.
+
+{{< example >}}
+<div class="alert alert-success" role="alert">
+  <h4 class="alert-heading">Well done!</h4>
+  <p>Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.</p>
+  <hr>
+  <p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
+</div>
+{{< /example >}}
+
+
+### Dismissing
+
+Using the alert JavaScript plugin, it's possible to dismiss any alert inline. Here's how:
+
+- Be sure you've loaded the alert plugin, or the compiled Bootstrap JavaScript.
+- If you're building our JavaScript from source, it [requires `util.js`]({{< docsref "/getting-started/javascript#util" >}}). The compiled version includes this.
+- Add a dismiss button and the `.alert-dismissible` class, which adds extra padding to the right of the alert and positions the `.close` button.
+- On the dismiss button, add the `data-dismiss="alert"` attribute, which triggers the JavaScript functionality. Be sure to use the `<button>` element with it for proper behavior across all devices.
+- To animate alerts when dismissing them, be sure to add the `.fade` and `.show` classes.
+
+You can see this in action with a live demo:
+
+{{< example >}}
+<div class="alert alert-warning alert-dismissible fade show" role="alert">
+  <strong>Holy guacamole!</strong> You should check in on some of those fields below.
+  <button type="button" class="close" data-dismiss="alert" aria-label="Close">
+    <span aria-hidden="true">&times;</span>
+  </button>
+</div>
+{{< /example >}}
+
+## JavaScript behavior
+
+### Triggers
+
+Enable dismissal of an alert via JavaScript:
+
+```js
+$('.alert').alert()
+```
+
+Or with `data` attributes on a button **within the alert**, as demonstrated above:
+
+```html
+<button type="button" class="close" data-dismiss="alert" aria-label="Close">
+  <span aria-hidden="true">&times;</span>
+</button>
+```
+
+Note that closing an alert will remove it from the DOM.
+
+### Methods
+
+| Method | Description |
+| --- | --- |
+| `$().alert()` | Makes an alert listen for click events on descendant elements which have the `data-dismiss="alert"` attribute. (Not necessary when using the data-api's auto-initialization.) |
+| `$().alert('close')` | Closes an alert by removing it from the DOM. If the `.fade` and `.show` classes are present on the element, the alert will fade out before it is removed. |
+| `$().alert('dispose')` | Destroys an element's alert. |
+
+```js
+$('.alert').alert('close')
+```
+
+### Events
+
+Bootstrap's alert plugin exposes a few events for hooking into alert functionality.
+
+| Event | Description |
+| --- | --- |
+| `close.bs.alert` | This event fires immediately when the `close` instance method is called. |
+| `closed.bs.alert` | This event is fired when the alert has been closed (will wait for CSS transitions to complete). |
+
+```js
+$('#myAlert').on('closed.bs.alert', function () {
+  // do something...
+})
+```
