css - @keyframes 能接受参数吗？

问题描述

@keyframes around { from { margin-left: 100%; } to { margin-left: -5em; } }

那个-5em应该是参数传进去的？可以解决吗？

问题解答

设置自定义CSS属性结合var函数实现，自定义属性以--符号开头例子

<!DOCTYPE html><html lang='en'><head> <meta charset='UTF-8'> <title>Title</title> <style>@keyframes around { from {margin-left: 100%; } to {margin-left: var(--margin-left); }}.main{ position: absolute; left:0p; top:0px; width: 200px; height: 200px; background-color: #7C2845; color:#ffffff; --margin-left:-5em;}.main.active{ animation-name: around; animation-duration: 1s; animation-direction: alternate; animation-iteration-count: infinite;} </style></head><body> <p class='main active'>TEST </p></body></html>
