Hi Sarah, I am trying to make all my Avatars circular, so I copied these codes:
img.avatar {
-webkit-border-radius: 50%;
-moz-border-radius: 50%;
-ms-border-radius: 50%;
-o-border-radius: 50%;
border-radius: 50%;
-webkit-box-shadow: 0 1px 0 #fff;
-moz-box-shadow: 0 1px 0 #fff;
box-shadow: 0 1px 0 #fff;
}

And I put them in my theme style css, but nothing has changed. Can you please help and point me the right direction?

Thanks,

Dsvay
