@keyframes around {
from {
margin-left: 100%;
}
to {
margin-left: -5em;
}
}
那個-5em應該是參數傳進去的?可以解決嗎?

設定自訂CSS屬性結合var函數實現,自訂屬性以--符號開頭
範例
<!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>
