【问题描述】:
在我创建的这个JS Fiddle 中,元素div#load 及其::before 和::after 伪元素都是动画的。但是,如果我将 div 的 animation-play-state 更改为 'paused',则只有主要元素停止移动。伪元素继续它们的动画,直到我在 Inspector 中将鼠标悬停在它们上方。如果我再次将其更改为'running',则三个都将继续动画。
在谷歌浏览器中不是这种情况,伪元素应该停止。
我应该怎么做才能完全停止动画?
HTML:
<div id="load"></div>
<input type="button" value="Stop Animation" onclick="load.style.animationPlayState='paused';" />
<input type="button" value="Continue Animation" onclick="load.style.animationPlayState='running';" />
CSS:
#load {
position: absolute;
left: 50%;
top: 50%;
margin-left: -16px;
margin-top: -16px;
width: 24px;
height: 24px;
border: 4px solid transparent;
border-left: 4px solid rgba(255,0,0,0.5);
border-radius: 16px;
-webkit-animation: r 4s linear 0s infinite;
-moz-animation: r 4s linear 0s infinite;
animation: r 4s linear 0s infinite;
}
#load::before, #load::after {
content: "";
position: absolute;
left: -4px;
top: -4px;
width: 24px;
height: 24px;
border: 4px solid transparent;
border-radius: 16px;
-webkit-animation-play-state: inherit !important;
-moz-animation-play-state: inherit !important;
animation-play-state: inherit !important;
}
#load::before {
border-top: 4px solid rgba(0,0,255,0.5);
-webkit-animation: r 5s linear 0s infinite;
-moz-animation: r 5s linear 0s infinite;
animation: r 5s linear 0s infinite;
}
#load::after {
border-right: 4px solid rgba(0,255,0,0.5);
-webkit-animation: r 1600ms linear 0s infinite reverse;
-moz-animation: r 1600ms linear 0s infinite reverse;
animation: r 1600ms linear 0s infinite reverse;
}
@-webkit-keyframes r {
from { transform: rotate(0deg); }
to { transform: rotate(360deg);}
}
@-moz-keyframes r {
from { transform: rotate(0deg); }
to { transform: rotate(360deg);}
}
@keyframes r {
from { transform: rotate(0deg); }
to { transform: rotate(360deg);}
}
