HELL , I think this will fix it ૮ ◜ᵕ◝ ྀིა (if you're talking about the background of the pfp)

.profile_avatar {
  width: 100px;
  height: 100px;
  animation: float 3s ease-in-out infinite;
}

@keyframes float {
  0% {
    transform: translateY(0);
  }
  50% {
    transform: translateY(-20px);
  }
  100% {
    transform: translateY(0);
  }
}

uahhhhhh css is so annoying geulp, but also words just not registering either . . . But like this?
