The sbb-alert is a component which should be used to display important messages to a client.
Multiple instances of this component can be used within
the sbb-alert-group component.
Slots
The text content is projected using and unnamed slot, while the title uses the slot named title or alternatively the titleContent property.
The component can optionally display a sbb-icon at the component start using the iconName property or via custom content using the icon slot.
<sbb-alert title-content="Interruption between Berne and Olten" icon-name="disruption">
Between Bern and Olten from 03.11.2021 to 05.12.2022 each time from 22:30 to 06:00 o'clock
construction work will take place. You have to expect changed travel times and changed
connections.
</sbb-alert>
<sbb-alert>
<span slot="title">Interruption between Berne and Olten</span>
<sbb-icon slot="icon" name="disruption"></sbb-icon>
Between Bern and Olten from 03.11.2021 to 05.12.2022 each time from 22:30 to 06:00 o'clock
construction work will take place. You have to expect changed travel times and changed
connections.
</sbb-alert>Interactions
It's possible to place an action, which by clicking navigates somewhere to display more information.
This can be done using the linkContent property combined with the href one.
The target and rel property are also configurable via the self-named properties.
<sbb-alert
title-content="Interruption"
link-content="Show more"
href="https://www.sbb.ch"
target="_blank"
>
...
</sbb-alert>The sbb-alert can optionally be hidden by a user, if the readonly prop is not set.
Please note that clicking on the close button does not remove it from the DOM, this would be the responsibility
of the library consumer to do it by reacting to the specific event.
See also the sbb-alert-group
which automatically removes an alert after clicking the close button.
<sbb-alert title-content="Interruption between Berne and Olten" readonly>
Between Bern and Olten from 03.11.2021 to 05.12.2022 each time from 22:30 to 06:00 o'clock
construction work will take place. You have to expect changed travel times and changed
connections.
</sbb-alert>Style
Users can choose between two size, m (default) and l.
<sbb-alert size="l"> ... </sbb-alert>Accessibility
Accessibility is mainly done by wrapping the alerts into the sbb-alert-group.
The description text is wrapped into an <p> element to guarantee the semantic meaning.
Avoid slotting block elements (e.g. <div>) as this violates semantic rules and can have negative effects on screen readers.
