如何使图像的覆盖向右滑动以在css3动画中显示该图像

Question

我正在做一个CSS的页面加载器，我想出现的标志与滑动覆盖到右边，喜欢的加载栏，但这里想要使加载标志而不是酒吧。下面是我的代码

.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>

我希望滑动它的底图:之前慢慢地滑到右边

    height: 300px;
    position: absolute;
    top: 10px;
/*     left: 300px; */
    z-index: 99;
    background: rgba(0, 0, 0, 0.6);
  transition: all 0.3s linear;
}
.outer:hover .underlay:before { 
  width: 0;
}

<div class="outer">
<div class="underlay">
    <img src="https://i.ibb.co/8M3cFG4/bbb.jpg" alt="loading logo">

</div>

.underlay:before{
    content:"";
    width: 300px;
    height:300px;
    position: absolute;
    top: 200px;
    left:0;
    z-index: 99;
    background: rgba(0,0,0,0.9);
    animation-name: slide;
    animation-duration: 7s;
    animation-timing-function: linear;
}
@-webkit-keyframes slide{
    0%{
        left:510px;
    }
    100%{
        left:850px;
    }
}
