typecho内嵌B站视频

第一步 在主题的自定义CSS里面加入以下代码

/*视频挂载*/

.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
}

第二步 将原来的内嵌代码插入 class="iframe_video"

<iframe src="//player.bilibili.com/player.html?aid=81707180&bvid=BV1NJ41187Vx&cid=139804096&page=1" scrolling="no" border="0" frameborder="no" framespacing="0" allowfullscreen="true"> </iframe>

改为

<iframe class="iframe_video" src="//player.bilibili.com/player.html?aid=81707180&bvid=BV1NJ41187Vx&cid=139804096&page=1" scrolling="no" border="0" frameborder="no" framespacing="0" allowfullscreen="true"> </iframe>

这样就可以将原来PC端较小的窗口更改为比较适合观看的大小
