仅使用CSS自动放大img

这很简单。您可以在jsfiddle.net的此链接上看到DEMO

  


@keyframes zoominoutsinglefeatured {
    0% {
        transform: scale(1,1);
    }
    50% {
        transform: scale(1.2,1.2);
    }
    100% {
        transform: scale(1,1);
    }
}

.cardcontainer img {
    animation: zoominoutsinglefeatured 1s infinite ;
}
