CSS keyframe animations code example

animation: name duration timing-function delay iteration-count direction fill-mode;

@keyframes name {
    0% {
        background-size: 100%;
    }

    50% {
        background-size: 120%;
    }

    100% {
        background-size: 100%;
    }
}

For iteration count, you can use “infinite” to make the animation loop.
