A simple danger alert - check it out!
A simple warning alert - check it out!

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.

1. Using the Dismissable="true", it’s possible to dismiss any alert inline.
Holy guacamole! You should check in on some of those fields below.
<Alert Color="AlertColor.Warning" Dismissable="true"> <strong>Holy guacamole!</strong> You should check in on some of those fields below. </Alert>
2. Manually we can close an alert with button click.
Holy guacamole! You should check in on some of those fields below.
<Alert @ref="warningAlert" Color="AlertColor.Warning">
<strong>Holy guacamole!</strong> You should check in on some of those fields below. <Button Color="ButtonColor.Primary" @onclick="CloseAlert">Close</Button>
</Alert>
@code {
Alert warningAlert = default!;
private async Task CloseAlert() => await warningAlert.CloseAsync();
}
NOTE
When an alert is dismissed, the element is completely removed from the page structure. If a keyboard user dismisses the alert using the close button, their focus will suddenly be lost and, depending on the browser, reset to the start of the page/document.
For this reason, we recommend subscribing to the OnClosed callback event and programmatically sets focus to the most appropriate location on the page.
