For Notifications and Alerts, first, create the Notification under the content type "Notifications" and add your content and any appropriate scheduling. Title the notification something that you can reference for when you place the notification on a page or within a region. (The title is NOT displayed in the notification).
*NOTE: You can schedule via scheduling options in the content item.
Next, create a Custom Block using the Notification Block Type and select the Notification you'd like to display.
Finally, place the block within a page via Layout Builder or using the Block Layout (regions).
There are three display options:
- Default — full width for the top bar or within the container if using within Layout Builder
- Emergency — bright red, larger text
- Floating — floats left within a page.
