+title: Toasts
+description: Push notifications to your visitors with a toast, a lightweight and easily customizable alert message.
+group: components
+toc: true
+---
+
+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.
+
+## Examples
+
+A basic toast can include a header (though it doesn't strictly need one) with whatever contents you like. The header is also `display: flex`, so `.mr-auto` and `.ml-auto` can be used for easy pushing of content, as well as all our flexbox utilities.

+{% capture example %}
+
+
+
+ Bootstrap
+ 11 mins ago
+
+
+ Hello, world! This is a toast message.
+
+
+{% endcapture %}
+{% include example.html content=example %}
+
+
+They're slightly translucent, too, so they blend over whatever they might appear over. For browsers that support `backdrop-filter`, we'll also attempt to blur the elements under a toast.

+
+
+ Hello, world! This is a toast message.
+
+
+{% endcapture %}
+{% include example.html content=example %}
+
+
+Plus, they'll easily stack.

+
+
+ Heads up, toasts will stack automatically
+
+
+{% endcapture %}
+{% include example.html content=example %}
+
+
+## Accessibility
+
+Toasts are intended to be small interruptions to your visitors or users, so to help those on screen readers, you should wrap your toasts in an [`aria-live` region](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Live_Regions). This allows screen readers the ability to see suggested interruptions without any visual cues.
+
+{% highlight html %}
+
+
...
+
+{% endhighlight %}
+
+## 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.`

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