我如何使图像幻灯片的叠加层正确显示在 css3 动画中

Question

我正在 CSS 中制作一个页面加载器，我想显示带有向右滑动覆盖的徽标，就像加载栏一样，但这里想要制作加载徽标而不是栏。所以这是我的代码

.underlay{
    width: 300px;
    height:300px;
    margin-left: 300px;
    margin-top: 15%;
 }
.underlay:before{
    content:"";
    width: 300px;
    height:300px;
    position: absolute;
    top: 15%;
    left: 300px;
    z-index: 99;
    background: rgba(0,0,0,0.9);
    animation-name: slide;
}

<div class="outer">
<div class="underlay">
    <img src="logo.png" alt="loading logo">
</div>
</div>

我希望滑动它underlay:before慢慢向右滑动
