## Link color

Use the `.alert-link` utility class to quickly provide matching colored links within any alert.

This is a primary alert with an example link. Give it a click if you like.

                          <div class="alert alert-primary" role="alert">
                            This is a primary alert with <a href="#0" class="alert-link">an example link</a>. Give it a click if you like.
                          </div>

## With Icon

Information: Alert with icon

                          <div class="alert alert-primary media" role="alert">
                            <i class="fas fa-info-circle mt-1 me-1"></i>
                            <div class="media-body" role="alert">
                              This is a primary alert with <a href="#0" class="alert-link">an example link</a>. Give it a click if you like.
                            </div>
                          </div>

## Dismissing

Use `.alert-dismissible` class for `.alert`.

Holy guacamole! You should check in on some of those fields below.

                          <div class="alert alert-warning alert-dismissible fade show pe-5" role="alert">
                            <strong>Holy guacamole!</strong> You should check in on some of those fields below.
                            <button type="button" class="close p-2" data-dismiss="alert" aria-label="Close">

                            </button>
                          </div>

## Additional content

Alerts can also contain additional HTML elements like headings, paragraphs and dividers.

#### Well done!

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.

                          <div class="alert alert-success" role="alert">
                            <h4 class="alert-heading">Well done!</h4>
                            <p class="text-inherit">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="text-inherit mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
                          </div>

## JavaScript behavior

##### Triggers

Enable dismissal of an alert via JavaScript:

                    var alertList = document.querySelectorAll('.alert')
                    alertList.forEach(function (alert) {
                      new bootstrap.Alert(alert)
                    })

Or with `data` attributes on a button within the alert, as demonstrated above:

                    <button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>

Note that closing an alert will remove it from the DOM.

## Methods

You can create an alert instance with the alert constructor, for example:

                    var myAlert = document.getElementById('myAlert')
                    var bsAlert = new bootstrap.Alert(myAlert)

This makes an alert listen for click events on descendant elements which have the `data-bs-dismiss="alert"` attribute. (Not necessary when using the data-api’s auto-initialization.)

Method | Description
--- | ---
`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.
`dispose` | Destroys an element's alert. (Removes stored data on the DOM element)
`getInstance` | Static method which allows you to get the alert instance associated to a DOM element, you can use it like this: `bootstrap.Alert.getInstance(alert)`

                    var alertNode = document.querySelector('.alert')
                    var alert = bootstrap.Alert.getInstance(alertNode)
                    alert.close()

## Events

Bootstrap’s alert plugin exposes a few events for hooking into alert functionality.

Event | Description
--- | ---
`close.bs.alert` | Fires immediately when the `close` instance method is called.
`closed.bs.alert` | Fired when the alert has been closed and CSS transitions have completed.

                    var myAlert = document.getElementById('myAlert')
                    myAlert.addEventListener('closed.bs.alert', function () {
                      // do something, for instance, explicitly move focus to the most appropriate element,
                      // so it doesn't get lost/reset to the start of the page
                      // document.getElementById('...').focus()
                    })
