Introduction
The badge component is most frequently used to signal status (online, offline, busy, etc) and whether there's notifications or not.

Position
Use the anchorOrigin prop to control the badge position to any corner of the child element.
<Badge

vertical: 'top',
horizontal: 'right',
}}

Inset
The badgeInset prop gives you precise control of the badge's position.
Use a string value matching the inset CSS property syntax.

Accessibility
Make sure to always provide a meaningful description to the aria-label prop, regardless if it is on the badge or the component wrapping it.
<IconButton color="neutral" aria-label={notificationsLabel(100)}>
<Badge badgeContent={100} badgeInset="-20%">
<MailIcon />
</Badge>
</IconButton>

Unstyled
The component also comes with an unstyled version. It's ideal for doing heavy customizations and minimizing bundle size.
