# Toasts

Push notifications to your visitors with a toast, a lightweight and easily customizable alert message.

Toasts are lightweight notifications designed to mimic the push notifications that have been popularized by mobile and desktop operating systems. They’re built with flexbox, so they’re easy to align and position.

Bootstrap Toasts documentation

## Basic

To encourage extensible and predictable toasts, we recommend a header and body. Toast headers use `display: flex`, allowing easy alignment of content thanks to our margin and flexbox utilities.

Toasts are as flexible as you need and have very little required markup. At a minimum, we require a single element to contain your “toasted” content and strongly encourage a dismiss button.

Hello, world! This is a toast message.

                          <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
                            <div class="toast-header">
                              <img src="..." class="rounded me-2" alt="...">
                              <strong class="me-auto">Bootstrap</strong>

                              <button type="button" class="ms-2 mb-1 btn-close" data-dismiss="toast" aria-label="Close"></button>
                            </div>
                            <div class="toast-body">
                              Hello, world! This is a toast message.
                            </div>
                          </div>

## Stacking

When you have multiple toasts, we default to vertically stacking them in a readable manner.

Heads up, toasts will stack automatically

                            </div>
                            <div class="toast-body">

                            </div>
                          </div>

## Placement

Place toasts with custom CSS as you need them. The top right is often used for notifications, as is the top middle. If you’re only ever going to show one toast at a time, put the positioning styles right on the `.toast`.

                                <button type="button" class="ms-2 mb-1 btn-close" data-dismiss="toast" aria-label="Close"></button>
                              </div>
                              <div class="toast-body">
                                See? Just like this.
                              </div>
                            </div>
                          </div>

## JavaScript behavior

##### Usage

Initialize toasts via JavaScript:

                    var toastElList = [].slice.call(document.querySelectorAll('.toast'))
                    var toastList = toastElList.map(function (toastEl) {
                      return new bootstrap.Toast(toastEl, option)
                    })

##### Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-bs-`, as in `data-bs-animation=""`.

Name | Type | Default | Description
--- | --- | --- | ---
`animation` | boolean | `true` | Apply a CSS fade transition to the toast
`autohide` | boolean | `true` | Auto hide the toast
`delay` | number | `5000` | Delay hiding the toast (ms)

## Methods

#### Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

See our JavaScript documentation for more information.

##### show

Reveals an element’s toast. Returns to the caller before the toast has actually been shown (i.e. before the `shown.bs.toast` event occurs). You have to manually call this method, instead your toast won’t show.

                    toast.show()

##### hide

Hides an element’s toast. Returns to the caller before the toast has actually been hidden (i.e. before the `hidden.bs.toast` event occurs). You have to manually call this method if you made `autohide` to `false`.

                    toast.hide()

##### dispose

Hides an element’s toast. Your toast will remain on the DOM but won’t show anymore.

                    toast.dispose()

##### Events

Event type | Description
--- | ---
`show.bs.toast` | This event fires immediately when the `show` instance method is called.
`shown.bs.toast` | This event is fired when the toast has been made visible to the user.
`hide.bs.toast` | This event is fired immediately when the `hide` instance method has been called.
`hidden.bs.toast` | This event is fired when the toast has finished being hidden from the user.

                    var myToastEl = document.getElementById('myToast')
                    myToastEl.addEventListener('hidden.bs.toast', function () {
                      // do something...
                    })
