Avatars are circular components that usually wrap an image or icon. They can be used to represent a person or an object.

Avatars can be used by themselves or inside of any element. If placed inside of an ion-chip or ion-item, the avatar will resize to fit the parent component. To position an avatar on the left or right side of an item, set the slot to start or end, respectively.
