Additional content #

Alert can also incorporate supplementary HTML elements like heading, paragraph, and divider.

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>
  <div>
    An example alert with an icon
  </div>
</CAlert>

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 !default;
$alert-padding-x:               $spacer !default;
$alert-margin-bottom:           1rem !default;
$alert-border-radius:           $border-radius !default;
$alert-link-font-weight:        $font-weight-bold !default;
$alert-border-width:            $border-width !default;
$alert-bg-scale:                -80% !default;
$alert-border-scale:            -70% !default;
$alert-color-scale:             40% !default;
$alert-dismissible-padding-r:   $alert-padding-x * 3 !default; // 3x covers width of x plus default padding on either side
