Question

我的动画在完成动画后不断消失。我已经按照其他问题的答案，但它仍然没有帮助。我的CSS如下：

   .upvote-object {
        width: 50px;
        height: 62.5px;
        background: url('/icons/upvote.png') left center no-repeat;
        background-size: 50px 62.5px;

        &.upvoted {
            background: url('/icons/upvoted.png') left center no-repeat;
            background-size: 50px 62.5px !important;
        }
    }
    .ani-upvote {
        background: url('/icons/upvote-sprite.png') left center no-repeat;
        background-size: 1700px 62.5px;

        animation: play 3s steps(34);
        animation-fill-mode: forwards;
        -webkit-animation-fill-mode: forwards;
        opacity: 1;
    }

    @keyframes play {
        100% {
          background-position: -1700px;
          opacity: 1;
        }
    }
    @-webkit-keyframes play {
        100% {
          background-position: -1700px;
          opacity: 1;
        }
    }

我在我的HTML中调用它：

<div class="upvote-object ani-upvote"></div>

问题在于：JSFiddle

更新：也请知道动画也必须留在最后一帧！（绿色）

我得到了它的工作。但我不是CSS专家。所以我很抱歉无法解释它的工作原理。也许你知道为什么：）

.upvote-object {
    width: 50px;
    height: 62.5px;
    background: url('http://sstaging-parts.herokuapp.com/icons/upvote.png') left center no-repeat;
    background-size: 50px 62.5px;
    animation-fill-mode: forwards;
    -webkit-animation-fill-mode: forwards;
    opacity: 1;
}
.ani-upvote {
    background: url('http://staging-parts.herokuapp.com/icons/upvote-sprite.png') left center no-repeat;
    background-size: 1700px 62.5px;

    animation: play 2s steps(33); // changed the steps to 33
    animation-fill-mode: forwards;
    -webkit-animation-fill-mode: forwards;
    opacity: 1;
}

@keyframes play {
    100% { background-position: -1650px; opacity: 1; }
}
@-webkit-keyframes play {
    100% { background-position: -1650px; opacity: 1; } // Changed the position to -1650
}

<强>更新我得到了它的工作。我认为它与精灵及其停止动画的位置有关......如果这有意义的话。
