click that, hover over where u wanna edit, and itll show u the name
ie. hoverin over ur avatar is img#avatar.avatar or something so you'd use .avatar
it would look like
.avatar{
   border: 2px white;
   border-radius: 15px;
}
you can edit css from the inspect element page, this helps me find out what i broke and what will work
this would soften the edge of ur avatar and make it have a white border
u can dm me if u want more help :]

ps. yw for being active lol im v bored and i like css
