description: Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.
group: components
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.
{% capture example %}
{% for color in site.data.theme-colors %}
{% include callout-warning-color-assistive-technologies.md %}
Use the .alert-link
utility class to quickly provide matching colored links within any alert.
{% capture example %}
{% for color in site.data.theme-colors %}
Alerts can also contain additional HTML elements like headings, paragraphs and dividers.
{% capture example %}
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.
Whenever you need to, be sure to use margin utilities to keep things nice and tidy.
Using the alert JavaScript plugin, it's possible to dismiss any alert inline. Here's how:
util.js
]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util). The compiled version includes this..alert-dismissible
class, which adds extra padding to the right of the alert and positions the .close
button.data-dismiss="alert"
attribute, which triggers the JavaScript functionality. Be sure to use the <button>
element with it for proper behavior across all devices..fade
and .show
classes.You can see this in action with a live demo:
{% capture example %}
Enable dismissal of an alert via JavaScript:
{% highlight js %}
$('.alert').alert()
{% endhighlight %}
Or with data
attributes on a button within the alert, as demonstrated above:
{% highlight html %}
×
{% endhighlight %}
Note that closing an alert will remove it from the DOM.
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. |
$().alert('dispose') |
Destroys an element's alert. |
{% highlight js %}$(".alert").alert('close'){% endhighlight %}
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). |
{% highlight js %}
$('#myAlert').on('closed.bs.alert', function () {
// do something…
})
{% endhighlight %}
