代码如下：
<div style="position: relative; padding: 30% 45%;"> <iframe src="https://player.bilibili.com/player.html?aid=100456428&cid=171311599&page=1&as_wide=1&high_quality=1&danmaku=0" scrolling="no" border="0" frameborder="no" framespacing="0" allowfullscreen="true" style="position: absolute; width: 100%; height: 100%; left: 0; top: 0;" sandbox="allow-top-navigation allow-same-origin allow-forms allow-scripts"> </iframe> </div>只需修改期中的aid=100456428&cid=171311599&page=1为自己视频的就可以了。
