<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
        .round{
            width: 100px;
            height: 100px;
            border-radius: 100%;
            border: 1px solid;
            position: relative;
            overflow: hidden;
        }
        .round::after{
            content: "";
            width: 200px;
            height: 200px;
            background-color:#41c4f8 ;
            border-radius: 80px;
            position: absolute;
            left: -50px;
            top: var(--top, 100px);;
            animation:rote 4s  linear infinite ;
        }
        @keyframes rote {
            form{
                transform: rotate(0);
            }
            to{
                transform: rotate(360deg);
            }
        }
    </style>
</head>
<body>
    <div class="containers">
        <div class="round">
        </div>
        <input type="range" min="0"  max="100" value="0" onchange="change()" >
    </div>
</body>
<script>
    // 1、dom实现动态修改伪元素的样式
    var rangeDom = document.querySelector('input') 
    var roundDom = document.querySelector('.round')
    function change(){   
        roundDom.style.setProperty('--top',(100-rangeDom.value)+'px')    
    }
</script>
</html>
