打开bilibili的某个视频，然后找到嵌入代码

<iframe src="//player.bilibili.com/player.html?aid=64527692&cid=112026718&page=1" scrolling="no" border="0" frameborder="no" framespacing="0" allowfullscreen="true"> </iframe>

复制嵌入代码添加到文章。
然后在给iframe 这个标签添加 class="iframe_video" iframe_video这个类名

即为

<iframe class="iframe_video" <iframe......

之后就是添加样式css

/*视频挂载 https://dxoca.cn/front/257.html */

.iframe_video {
    position: relative;
    width: 100%;
}

@media only screen and (max-width: 767px) {
    .iframe_video {
        height: 15em;
    }
}

@media only screen and (min-width: 768px) and (max-width: 991px) {
    .iframe_video {
        height: 20em;
    }
}

@media only screen and (min-width: 992px) and (max-width: 1199px) {
    .iframe_video {
        height: 30em;
    }
}

@media only screen and (min-width: 1200px) {
    .iframe_video {
        height: 40em;
    }
}

.iframe_cross {
    position: relative;
    width: 100%;
    height: 0;
    padding-bottom: 75%
}

.iframe_cross iframe {
    position: absolute;
    width: 100%;
    height: 100%;
    left: 0;
    top: 0
}

大功告成
