Svelte Figma

Notices deliver System and Engagement messaging, informing the user about product or account statuses and related actions.

Accessibility

Section titled Accessibility
Item Applied to Description
aria-labelledby="[id]" .s-toast Used to reference the alert message within the dialog. If you are using .s-toast, this must be applied. (Source)
aria-hidden="[state]" .s-toast Informs assistive technologies (such as screen readers) if they should ignore the element. When applied to .s-toast, Stacks will use this attribute to show or hide the toast. (Source)
aria-label="[text]" .s-btn Labels the element for assistive technologies (such as screen readers). This should be used on any button that does not contain text content. (Source)
role="alert" .s-notice A form of live region which contains important, usually time-sensitive, information. Elements with an alert role have an implicit aria-live value of assertive and implicit aria-atomic value of true. (Source)
role="alertdialog" .s-toast The wrapping content area of an alert. Elements with the alertdialog role must use the aria-describedby attribute to reference the alert message within the dialog. (Source)
role="status" .s-notice A form of live region which contains advisory information but isn't important enough to justify an alert role. Elements with a status role have an implicit aria-live value of polite and implicit aria-atomic value of true. If the element controlling the status appears in a different area of the page, you must make the relationship explicit with the aria-controls attribute. (Source)

Styling child links

Section titled Styling child links

We recommend using descendent anchor classes, typically .s-anchors.s-anchors__inherit.s-anchors__underlined for notices containing links generated from markdown when you cannot manually generate the inner html.

<div class="s-notice s-notice__info" role="presentation">
    <span>Notice with <a href="#" class="s-link">default link style</a></span>
</div>
<div class="s-notice s-notice__info s-anchors s-anchors__inherit s-anchors__underlined" role="presentation">
    <span>Notice with <a href="#">custom link style</a></span>
</div>

Behaviors

Section titled Behaviors
Behavior Class Applied to Description
Inline .s-notice N/A Notice inserted within the content area.
Toast .s-toast Container Adds a container to properly fix a floating toast notice to the top-center of the page. These toasts typically disappear after a set time (i.e. 3 seconds)

Toast

Section titled Toast

Floating notices, but aligned to the top and center of the page and they disappear after a set time. Visibility is changed with animation by toggling between aria-hidden="true" and aria-hidden="false". When including a dismiss button the .s-notice--dismiss class should be applied to the button for toast-specific styling.

Usage Warning: We are phasing out Toasts due to significant accessibility barriers. Avoid this component for new features. Instead, prioritize integrated alternatives—such as component state changes or inline messages—to provide accessible feedback directly where the user is focused.
