Here's how: - -- Be sure you've loaded the alert plugin, or the compiled Bootstrap JavaScript. -- Add a [close button]({{< docsref "/components/close-button" >}}) and the `.alert-dismissible` class, which adds extra padding to the right of the alert and positions the close button. -- On the close button, add the `data-bs-dismiss="alert"` attribute, which triggers the JavaScript functionality. Be sure to use the `<button>` element with it for proper behavior across all devices. -- To animate alerts when dismissing them, be sure to add the `.fade` and `.show` classes. - -You can see this in action with a live demo: - -{{< example >}} -<div class="alert alert-warning alert-dismissible fade show" role="alert"> - <strong>Holy guacamole!</strong> You should check in on some of those fields below. - <button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button> -</div> -{{< /example >}} - -{{< callout warning >}} -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 including additional JavaScript that listens for the `closed.bs.alert` event and programmatically sets `focus()` to the most appropriate location in the page. If you're planning to move focus to a non-interactive element that normally does not receive focus, make sure to add `tabindex="-1"` to the element. -{{< /callout >}} - -## Sass - -### Variables - -{{< scss-docs name="alert-variables" file="scss/_variables.scss" >}} - -### Variant mixin - -Used in combination with `$theme-colors` to create contextual modifier classes for our alerts. - -{{< scss-docs name="alert-variant-mixin" file="scss/mixins/_alert.scss" >}} - -### Loop - -Loop that generates the modifier classes with the `alert-variant()` mixin. - -{{< scss-docs name="alert-modifiers" file="scss/_alert.scss" >}} - -## JavaScript behavior - -### Triggers - -Enable dismissal of an alert via JavaScript: - -```js -var alertList = document.querySelectorAll('.alert') -alertList.forEach(function (alert) { - new bootstrap.Alert(alert) -}) -``` - -Or with `data` attributes on a button **within the alert**, as demonstrated above: - -```html -<button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button> -``` - -Note that closing an alert will remove it from the DOM. - -### Methods - -You can create an alert instance with the alert constructor, for example: - -```js -var myAlert = document.getElementById('myAlert') -var bsAlert = new bootstrap.Alert(myAlert) -``` - -This makes an alert listen for click events on descendant elements which have the `data-bs-dismiss="alert"` attribute.
