我首先声明，俺不是原创。这个是我从皮皮社那里最先看到的，在夏末那里扒来的，我只是单纯的想学习代码。

代码如下：

<div class="post_content padding blur animated fadeIn">
    <!-- 视频播放容器 16:10 比例 -->
    <div style="max-width: 460px; width: 92%; margin: 24px auto; position: relative; height: 0; padding-bottom: 62.5%; border-radius: 8px; overflow: hidden; box-shadow: 0 4px 16px rgba(0,0,0,.15); background: #1a1a1a;">
        <video id="beautyVideo" controls poster="https://v2.xxapi.cn/api/wapmeinvpic" preload="metadata" style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; object-fit: cover; outline: none; border: none;">
            <source id="videoSource" src="https://wzapi.com/api/sjxjjsp?t=1777449316751" type="video/mp4">
            您的浏览器不支持视频播放，请更新浏览器
        </video>
    </div>

    <!-- 按钮容器 -->

        <button id="nextVideoBtn" style="padding: 11px 28px; border: 0; border-radius: 999px; background: #444950; color: #fff; font-size: 14px; cursor: pointer; transition: background 0.3s ease; box-shadow: 0 2px 8px rgba(0,0,0,.2);">重试中(1)...</button>
