Using Bootstrap's typical naming structure, you can create a standard avatar, or scale it up to different sizes based on what's needed.

Add an online or offline status indicator to show user's availability.

Change the shape of an avatar with the default Bootstrap image classes.

Change the proportional relationship between the width and height of an avatar to 4 by 3 with an .avatar-4by3 modifier.

You won't always have an image for every user, so easily use initials instead.

Easily group avatars of any size, shape and content with a single component. Each avatar can also use an <a> to link to the corresponding profile.
