CSS 关键帧动画回到初始状态

Question

我正在调用这样的动画：

document.getElementById('banner').className = "changeColorToIndigo";

然后我得到 CSS 属性:

div.changeColorToIndigo {
animation-duration: 1s;
animation-name: changeColorToIndigo;
animation-fill-mode: forwards;
}

以及关键帧动画：

@keyframes changeColorToIndigo {
from {background-color: #00BBD2;}
to {background-color: #3F51B5;}
}

但是动画完成后又回到初始状态，这是为什么？我已将填充模式设置为转发并指定 to (100%) 属性.

我已将您的代码放在 Fiddle 中，对我来说效果很好

HTML

<div id="banner"></div>

CSS

div{
    height: 40px;
    width: 40px;
    background-color: #00BBD2;
}

div.changeColorToIndigo {
    animation-name: changeColorToIndigo;
    animation-duration: 1s;
    animation-fill-mode: forwards;
}

@keyframes changeColorToIndigo {
    from {background-color: #00BBD2;}
    to {background-color: #3F51B5;}
}

jQuery

$(document).ready(function(){
    $('#banner').addClass('changeColorToIndigo');
})
