css - 如何停止关键帧动画

Question

你能告诉我如何停止关键帧动画吗？在下面的示例中，div 元素循环回到顶部并再次向下移动。能否在 div 达到 {} 条件后停止功能？

<style> 
div
{
    width:100px;
    height:100px;
    background:red;
    position:relative;
    animation:mymove 5s infinite;
    -webkit-animation:mymove 5s infinite; /* Safari and Chrome */
}

@keyframes mymove
{
    from {top:0px;}
    to {top:200px;}
}

@-webkit-keyframes mymove /* Safari and Chrome */
{
    from {top:0px;}
    to {top:200px;}
}
</style>

<div></div>

Answer 1

你可以使用 animation-fill-mode以 forwards 为值的属性。

来自MDN :

forwards
The target will retain the computed values set by the last keyframe encountered during execution. The last keyframe encountered depends on the value of animation-direction and animation-iteration-count.

给你:

div {
    -webkit-animation: mymove 5s forwards; /* Safari and Chrome */
    /* Add other vendor-prefixes if needed */
    animation: mymove 5s forwards;
}
