【今年份最温柔的儿歌】《我中有你 Ci sarà un po' di voi》安东尼亚诺小合唱团 Piccolo Coro dell Antoniano

一、参考：

《Bilibili 视频适应页面宽度》

https://sunete.github.io/tutorial/bilibili-video-adapts-to-the-width/

二、操作：

1.写一个b.css

    .responsive-video-container {
        position: relative;
        margin-bottom: 1em;
        padding-bottom: 56.25%;
        height: 0;
        overflow: hidden;
        max-width: 100%;
    }
    .responsive-video-container iframe{
        position: absolute;
        top: 0;
        left: 0;
        width: 100%;
        height: 100%;
    }

2.html修改

<!--b站视频css-->
<link rel="stylesheet" href="../static/css/b.css" th:href="@{/css/b.css}">

<!-- 测试插入b站视频 ------------------------------->
<div class="responsive-video-container">
<iframe src="//player.bilibili.com/player.html?aid=722218435&bvid=BV1CS4y1D7NK&cid=456652130&page=1&as_wide=1&high_quality=1&danmaku=0"
        scrolling="no" border="0" frameborder="no" framespacing="0" allowfullscreen="true"> </iframe>
</div>
