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.

Overview

Things to know when using the toast plugin:

  • If you're building our JavaScript from source, it requires Bootstrap util.js.
  • Toasts are opt-in for performance reasons, so you must initialize them yourself.
  • Please note that you are responsible for positioning toasts.
  • Toasts will automatically hide if you do not specify autohide: false.

Examples

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.

            
              <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
                <div class="toast-header">
                  <img src="..." class="rounded mr-2" alt="...">
                  <strong class="mr-auto">Space</strong>
                  <small>11 mins ago</small>
                  <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
                    <span aria-hidden="true">×</span>
                  </button>
                </div>
                <div class="toast-body">
                  Hello, world! This is a toast message.
                </div>
              </div>
            
          

Translucent

Toasts are slightly translucent, too, so they blend over whatever they might appear over. For browsers that support the backdrop-filter CSS property, we'll also attempt to blur the elements under a toast.

            
              <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
                <div class="toast-header">
                  <img src="..." class="rounded mr-2" alt="...">
                  <strong class="mr-auto">Space</strong>
                  <small class="text-muted">11 mins ago</small>
                  <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
                    <span aria-hidden="true">×</span>
                  </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.

            
              <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
                <div class="toast-header">
                  <img src="..." class="rounded mr-2" alt="...">
                  <strong class="mr-auto">Space</strong>
                  <small class="text-muted">just now</small>
                  <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
                    <span aria-hidden="true">×</span>
                  </button>
                </div>
                <div class="toast-body">
                  See? Just like this.
                </div>
              </div>

              <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
                <div class="toast-header">
                  <img src="..." class="rounded mr-2" alt="...">
                  <strong class="mr-auto">Space</strong>
                  <small class="text-muted">2 seconds ago</small>
                  <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
                    <span aria-hidden="true">×</span>
                  </button>
                </div>
                <div class="toast-body">
                  Heads up, toasts will stack automatically
                </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.

Space 11 mins ago
Hello, world! This is a toast message.
            
              <div aria-live="polite" aria-atomic="true" style="position: relative; min-height: 200px;">
                <div class="toast" style="position: absolute; top: 0; right: 0;">
                  <div class="toast-header">
                    <img src="..." class="rounded mr-2" alt="...">
                    <strong class="mr-auto">Space</strong>
                    <small>11 mins ago</small>
                    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
                      <span aria-hidden="true">×</span>
                    </button>
                  </div>
                  <div class="toast-body">
                    Hello, world! This is a toast message.
                  </div>
                </div>
              </div>
            
          

For systems that generate more notifications, consider using a wrapping element so they can easily stack.

            
              <div aria-live="polite" aria-atomic="true" style="position: relative; min-height: 200px;">
                <!-- Position it -->
                <div style="position: absolute; top: 0; right: 0;">

                  <!-- Then put toasts within -->
                  <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
                    <div class="toast-header">
                      <img src="..." class="rounded mr-2" alt="...">
                      <strong class="mr-auto">Space</strong>
                      <small class="text-muted">just now</small>
                      <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
                        <span aria-hidden="true">×</span>
                      </button>
                    </div>
                    <div class="toast-body">
                      See? Just like this.
                    </div>
                  </div>

                  <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
                    <div class="toast-header">
                      <img src="..." class="rounded mr-2" alt="...">
                      <strong class="mr-auto">Space</strong>
                      <small class="text-muted">2 seconds ago</small>
                      <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
                        <span aria-hidden="true">×</span>
                      </button>
                    </div>
                    <div class="toast-body">
                      Heads up, toasts will stack automatically
                    </div>
                  </div>
                </div>
              </div>
            
          

You can also get fancy with flexbox utilities to align toasts horizontally and/or vertically.

            
              <!-- Flexbox container for aligning the toasts -->
              <div aria-live="polite" aria-atomic="true" class="d-flex justify-content-center align-items-center" style="min-height: 200px;">

                <!-- Then put toasts within -->
                <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
                  <div class="toast-header">
                    <img src="..." class="rounded mr-2" alt="...">
                    <strong class="mr-auto">Space</strong>
                    <small>11 mins ago</small>
                    <button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
                      <span aria-hidden="true">×</span>
                    </button>
                  </div>
                  <div class="toast-body">
                    Hello, world! This is a toast message.
                  </div>
                </div>
              </div>
