Animation not working, what should I do?

Question

css

The animation does not work, I checked everything, ran it through the autoprefixer - it didn’t help, I don’t know what to do anymore, the browser is chrome.
Here is the animation code:
@-webkit-keyframes flip {
from {
-webkit-transform: perspective(400px) scale3d(1, 1, 1) translate3d(0, 0, 0)
rotate3d(0, 1, 0, -360deg);
transform: perspective(400px) scale3d(1, 1, 1) translate3d(0, 0, 0) rotate3d(0, 1, 0, -360deg);
-webkit-animation-timing-function: ease-out;
animation-timing-function: ease-out;
}
40% {
-webkit-transform: perspective(400px) scale3d(1, 1, 1) translate3d(0, 0, 150px)
rotate3d(0, 1, 0, -190deg);
transform: perspective(400px) scale3d(1, 1, 1) translate3d(0, 0, 150px)
rotate3d(0, 1, 0, -190deg);
-webkit-animation-timing-function: ease-out;
animation-timing-function: ease-out;
}
50% {
-webkit-transform: perspective(400px) scale3d(1, 1, 1) translate3d(0, 0, 150px)

transform: perspective(400px) scale3d(1, 1, 1) translate3d(0, 0, 150px)
rotate3d(0, 1, 0, -170deg);
-webkit-animation-timing-function: ease-in;

transform: perspective(400px) scale3d(0.95, 0.95, 0.95) translate3d(0, 0, 0)
rotate3d(0, 1, 0, 0deg);

}
to {
-webkit-transform: perspective(400px) scale3d(1, 1, 1) translate3d(0, 0, 0)

}
}
.animated.flip {
-webkit-backface-visibility: visible;
backface-visibility: visible;
-webkit-animation-name: flip;
animation-name: flip;
}
Then I assign a class to the element and nothing happens...
I would be very grateful for the help!

Add Duration

.animated.flip {
-webkit-backface-visibility: visible;
backface-visibility: visible;
-webkit-animation: flip 3s;
animation: flip 3s;
}
