css3动画模拟光标

.animation::after {    content:'';    display: block;    width:1px;    height:16px;    animation: blink 1s infinite steps(1, start)  }@keyframes blink { 0%{   background-color: white; } 50% {   background-color: black; } 100% {   background-color: white; }

给一个元素添加上class=“animation“ 就是看到一闪一闪的样子了
