Vue Alert Component
Vue alert component gives contextual feedback information for common user operations. The alert component is delivered with a bunch of usable and adjustable alert messages.
Other frameworks
CoreUI components are available as native Angular, Bootstrap (Vanilla JS), and React components. To learn more please visit the following pages.

Additional content

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.
<CAlert color="success" v-bind:visible="true">
<CAlertHeading>Well done!</CAlertHeading>
<p>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.</p>
<hr />
<p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
</CAlert>
Icons
Similarly, you can use flexbox utilities and CoreUI Icons to create alerts with icons. Depending on your icons and content, you may want to add more utilities or custom styles.
An example alert with an icon
<CAlert color="primary" class="d-flex align-items-center">
<svg class="flex-shrink-0 me-2" width="24" height="24" viewBox="0 0 512 512">
<rect width="32" height="176" x="240" y="176" fill="var(--ci-primary-color, currentColor)" class="ci-primary"></rect><rect width="32" height="32" x="240" y="384" fill="var(--ci-primary-color, currentColor)" class="ci-primary"></rect><path fill="var(--ci-primary-color, currentColor)" d="M274.014,16H237.986L16,445.174V496H496V445.174ZM464,464H48V452.959L256,50.826,464,452.959Z" class="ci-primary"></path>
</svg>

Dismissing
Alerts can also be easily dismissed. Just add the dismissible prop.
Go right ahead and click that dimiss over there on the right.
<CAlert color="warning" dismissible @close="alert">
<strong>Go right ahead</strong> and click that dimiss over there on the right.
</CAlert>
<script>
export default {
methods: {
alert () {
alert("👋 Well, hi there! Thanks for dismissing me.")
},
}
}
</script>
Customizing
CSS variables
Vue alerts use local CSS variables on .alert for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.
--cui-alert-bg: transparent;
--cui-alert-padding-x: #{$alert-padding-x};
--cui-alert-padding-y: #{$alert-padding-y};
--cui-alert-margin-bottom: #{$alert-margin-bottom};
--cui-alert-color: inherit;
--cui-alert-border-color: transparent;
--cui-alert-border: #{$alert-border-width} solid var(--cui-alert-border-color);
--cui-alert-border-radius: #{$alert-border-radius};
How to use CSS variables
const vars = {
'--my-css-var': 10,
'--my-another-css-var': "red"
}
return <CAlert :style="vars">...</CAlert>
SASS variables
$alert-padding-y: $spacer;
$alert-padding-x: $spacer;
$alert-margin-bottom: 1rem;
$alert-border-radius: $border-radius;
$alert-link-font-weight: $font-weight-bold;
$alert-border-width: $border-width;
$alert-bg-scale: -80%;
$alert-border-scale: -70%;
$alert-color-scale: 40%;
$alert-dismissible-padding-r: $alert-padding-x * 3; // 3x covers width of x plus default padding on either side
