Hii thank you! This is what i use:

.profile_avatar { animation: name 2s ease 0s 1 normal forwards; animation-iteration-count: infinite; border-radius: 3px; outline: 1px solid #a90412; box-shadow: 1px 0px 19px 4px rgba(213, 112, 45, 4); }

@keyframes name { 0% { transform: scale3d(1, 1, 1); }

30% {
    transform: scale3d(0.75, 1.25, 1);
}

40% {
    transform: scale3d(1.25, 0.75, 1);
}

50% {
    transform: scale3d(0.85, 1.15, 1);
}

65% {
    transform: scale3d(1.05, 0.95, 1);
}

75% {
    transform: scale3d(0.95, 1.05, 1);
}

100% {
    transform: scale3d(1, 1, 1);
}
