The Avatar component is used to represent a user, and displays the profile picture, initials or fallback icon.
Standard Avatar comes in a single size.
You can use the avatar class on your figure tag to get the standard avatar.
The Avatar component comes in different sizes. You can use the avatar-xs for extra small avatar, avatar-sm for small avatar, avatar-md for a medium-sized avatar and avatar-lg class for a large avatar alongside the avatar class.
When an Avatar does not contain an image, usually a Text Avatar with user's initials are used. You can use the avatar-text class alongside any of the above defined classes to get a Text Avatar component.
