The Avatar is basically a smaller image compared to the cover image that represents what the group is all about. To make the group stand out, group admins can upload an image to create a group avatar. This image can be displayed to the left/right of the group name when users are viewing the group page.
Note: This widget is available only when building your Group page.
Styling the Avatar Widget
You can style the avatar image with different settings such as the Alignment(left,right,center), Size(full,thumb), Width(max 200) as well as Box shadow and Border under different states (normal and hover).
You can also define its margins in the advanced tab.
