思路很简单，实现方法有很多很多。但是大体思路与实现方法都类似：渐变色 + 动画，主要区别在动画的具体实现

0、HTML 结构

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>流光按钮</title>
</head>
<body><div class="wrapper"><div class="btn">按钮</div></div>
</body>
</html>

1-1、CSS 实现一

<style>*{padding: 0;margin: 0;}@property --rotate{syntax: "<angle>";initial-value: 20deg;inherits: false;}body{background-color: rgba(243, 243, 243);}.wrapper{position: relative;padding: 50px;background-color: rgb(0, 0, 0);z-index: -4;height: 500px;}.wrapper .btn{overflow: hidden;position: relative;text-align: center;border-radius: 7px;width: 100px;height: 50px;line-height: 50px;font-size: 22px;color: white;user-select: none;margin: 50px auto;}.btn::before{position: absolute;border-radius: 7px;content: "";inset: -20px;background: linear-gradient(var(--rotate), transparent 1%, rgb(255, 0, 191) , #00b7ff,  rgba(255, 0, 34, 0.719), transparent 98%);transform-origin: bottom left;z-index: -2;transition: all .4;animation: spin 2.4s linear infinite;transform-origin: 50% 50%;}.btn::after{content: "";position: absolute;border-radius: 8px;background-color: rgb(41, 41, 41);inset: 3px;z-index: -1;}@keyframes spin {0%{--rotate: 0deg;}100%{--rotate: 360deg;}}
</style>

1-2、CSS 实现二

  <style>*{padding: 0;margin: 0;}body{background-color: rgba(243, 243, 243);}.wrapper{position: relative;padding: 50px;background-color: rgb(0, 0, 0);z-index: -4;height: 500px;}.wrapper .btn{overflow: hidden;position: relative;text-align: center;border-radius: 7px;width: 100px;height: 50px;line-height: 50px;font-size: 22px;color: white;user-select: none;margin: 50px auto;}.btn::before{position: absolute;border-radius: 7px;content: "";inset: -20px;background: linear-gradient(0deg, transparent 1%, rgb(255, 0, 191) , #00b7ff,  rgba(255, 0, 34, 0.719), transparent 98%);transform-origin: bottom left;z-index: -2;transition: all .4;animation: spin 2.4s linear infinite;transform-origin: 50% 50%;}.btn::after{content: "";position: absolute;border-radius: 8px;background-color: rgb(41, 41, 41);inset: 3px;z-index: -1;}@keyframes spin {0%{transform: rotate(0deg);}100%{transform: rotate(360deg);}}</style>
