Shimmer effect

Not sure this will stay in, but I think this is a fun little effect, which adds a tiny eye-catcher to the Pro icon:

It has more pause in between the effect in the actual implementation, than the gif above.

Created entirely with CSS:

.picu-pro-box__icon {
    …
    background: linear-gradient(-45deg, #027791 40%, #f2fafb 50%, #027791 60%);
    background-size: 300%;
    background-position-x: 100%;
    animation: shimmer 5s infinite linear;
    animation-delay: 3s;
}

@keyframes shimmer {
    12%, 100% {
        background-position-x: 0%
    }
    0% {}
    10% {}
}
