Roles & attributes

The following list describes roles and attributes that component already has.

Roles and attributes

Component	Attribute	Usage
NoticeBubbleContainer	role="region", aria-label="Notifications"	Defines a landmark, so that users can easily navigate to it and access elements inside.
NoticeBubbleContainer	aria-live="polite"	Instructs the screen reader to announce changes inside the container whenever the user is idle.
Bubble.Content	role="alert" (only with type="warning")	Instructs the screen reader to announce the changes immediately, interrupting other processes.

Considerations for developers

• NoticeBubble automatically grabs keyboard focus if there're any interactive elements beside the Close button. In this case, when the notice is closed, you have to set focus back on the element that triggered it (refer to our examples). If that element doesn't exist anymore, set focus on its parent landmark.
• Don't trap keyboard focus in the NoticeBubble. Users should be able to navigate in and out freely.
