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 documentationTo 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.
<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>
<small>11 mins ago</small>
<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>
When you have multiple toasts, we default to vertically stacking them in a readable manner.
<div class="toast fade show mb-3" 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>
<small>just now</small>
<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 class="toast fade show" 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>
<small>2 seconds ago</small>
<button type="button" class="ms-2 mb-1 btn-close" data-dismiss="toast" aria-label="Close"></button>
</div>
<div class="toast-body">
Heads up, toasts will stack automatically
</div>
</div>
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.
<div aria-live="polite" aria-atomic="true" style="position: relative; min-height: 200px;">
<div class="toast fade show" role="alert" aria-live="assertive" aria-atomic="true" style="position: absolute; top: 0; right: 0;">
<div class="toast-header">
<img src="..." class="rounded me-2" alt="...">
<strong class="me-auto">Bootstrap</strong>
<small>just now</small>
<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>
Initialize toasts via JavaScript:
var toastElList = [].slice.call(document.querySelectorAll('.toast'))
var toastList = toastElList.map(function (toastEl) {
return new bootstrap.Toast(toastEl, option)
})
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-bs-, as in data-bs-animation="".

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