Overview

‘Avatar` can be used to represent users and organizations on GitHub.

  • Use the default circle avatar for users, and the square shape

for organizations or any other non-human avatars.

  • By default, ‘Avatar` will render a static `<img>`. To have `Avatar` function as a link, set the `href` which will wrap the `<img>` in a `<a>`.

  • Set ‘size` to update the height and width of the `Avatar` in pixels.

  • To stack multiple avatars together, use <%= link_to_component(Primer::Beta::AvatarStack) %>.
