Bootstrap 5 provides an easy way to create predefined alert messages:
Alerts are created with the .alert
class, followed by one of the contextual classes .alert-success
, .alert-info
, .alert-warning
, .alert-danger
, .alert-primary
, .alert-secondary
, .alert-light

:
<div class="alert alert-success">
<strong>Success!</strong> Indicates a successful or positive action.
</div>

<div class="alert alert-success">

</div>

to a link or a button element (when you click on this the alert box will disappear).
<div class="alert alert-success alert-dismissible">
<button type="button" class="btn-close" data-bs-dismiss="alert"></button>
<strong>Success!</strong> This alert box could indicate a successful or positive action.
